About

The R&S®HMP power supplies are primarily designed for industrial use. With two, three or four output channels and up to 10 A output current per channel, these rugged instruments are ideal for a wide variety of applications. They offer high efficiency with low residual ripple and many protection functions.

image

The R&S®HMP power supply family consists of four models. The R&S®HMP2020 two-channel power supply and the R&S®HMP2030 three-channel power supply deliver up to 188 W total output power, the three-channel R&S®HMP4030 and the four-channel R&S®HMP4040 offer a maximum output power of 384 W. The total load can be distributed as desired over the separate channels. Depending on the model, up to 80 W or 160 W of channel power is available – in any voltage/current distribution.

image

Up to four galvanically isolated, floating output channels with overload and short-circuit protection are available, depending on the instrument type. The channels can be connected in series or parallel to obtain higher voltages or currents. The R&S®HMP4040, for example, offers a maximum voltage of 128 V or a maximum current of 40 A. All basic functions of the R&S®HMP power supplies are directly accessible on the front panel. The rotary knob plays a key role. It is used to set the voltage, current and limit values for the various protection functions.

image

The channel keys light up in different colors to indicate the operating conditions of the channels. All channels can be simultaneously switched on or off with the “Output” key, which lights up white when it is "on". Active outputs light up green in constant voltage mode and red in constant current mode. The R&S®HMP power supplies offer a variety of protection functions to prevent damage to the instrument and the DUT. You can separately set the maximum current (electronic fuse, overcurrent protection/OCP) or the maximum voltage (overvoltage protection/OVP) for each channel. The output channels switch off when either of their set limits is reached.

image

Overtemperature protection (OTP) prevents the instrument from overheating. In industrial applications, power supplies are often installed in 19-inch racks. The R&S®HZ42 and R&S®HZP91 rack adapters are available for this purpose. Additional connections for all channels (including sense lines) are provided on the rear panel to simplify use in system cabinets.

 

The R&S®HMP power supplies are equipped with a dual USB/LAN interface as standard. This interface can optionally be replaced by a dual RS-232/USB interface or a GPIB (IEEE488) interface

  • Thanks for the link !

    The R&S document provides a nice "at a glance" comparison of major specifications and operational features.  The HMP4040 is a beefier supply for sure.  Given that, there are plenty more comparisons to be made beyond those in the R&S document including usability, remote support, data logging, transient recovery . . . price . . .

     

    I also have a B&K 9130 triple output programmable supply for comparison (although I think the 9130 model has been retired and replaced with a newer version).

     

    From my perspective a comparative Road Test between supplies (R&S, Keysight, B&K, etc.) would be helpful to those in the market for a new programmable supply.  Other than max V and I, the specs are pretty similar between the R&S and Keysight products, so the deciding factors might be those that are not mentioned in the R&S comparison document. I'm thinking that honest and transparent comparative reviews from element14 members would help make purchase decisions easier for some. 

  • It looks like everyone was planning to compare it to the Keysight and R&S have already done that!

     

    I've got the E36312A rather than everyone else's 3A. Although, having just been lucky enough to have done the RTM3004 road test I was probably going to leave this to somebody else.

  • This PSU could deliver up to 40A or 128V!

  • I suspect HO732 will come preinstalled based on the review description, even though the image seems to show the HO740 on the rear panel ... the rest of the accessories probably won't be supplied as is normal for RoadTests.

     

    - Gough

  • I would guess that none of those would be included apart from the first one which is installed as standard. The 2U rack mount kit isn't even appropriate for this model.

  • quite a big list of specs with a bunch of recommended accessories which can go with this.

    image

    Recommended accessories list

     

    R&SRegisteredHO732   Dual interface ethernet/USB

    R&SRegisteredHO740   Interface IEEE-488 (GPIB), galvanically isolated

    R&SRegisteredHZ10S   5 x silicone test lead (measurement connection in black)

    R&SRegisteredHZ10R   5 x silicone test lead (measurement connection in red)

    R&SRegisteredHZ10B   5 x silicone test lead (measurement connection in blue)

    R&SRegisteredHZ42    2RU 19“ rackmount kit

    R&SRegisteredHZ72    GPIB-cable 2m

    R&SRegisteredHZP91   19“ rackmount kit 4RU

     

    I wonder how many of these will be given away with the PSU?

  • Road Tests like this immediately get me excited!  As a life long technologist, how can I not be excited by awesome opportunities to evaluate high quality test equipment?

     

    When I read that this power supply was "based on a classical transformer concept" and that it delivered up to 10 A on 4 separate outputs, my first thought was "yikes, is my bench sturdy enough to support the weight of the transformer?".  I looked up the weight and was surprised that it only tips the scale at 12.8 kg (28.2 lb) which isn't too much more than my Keysight E36313A triple output supply which weighs 9.8 kg (21.6 lb).

     

    So my bench won't collapse if I load it up with an R&S HMP4040. image

    Best start thinking about ways to evaluate all of the robust capabilities of this supply and compare it with the E36313A.

  • Programmable <3.

    I will not be playing along with the Road Test, but secretly hope that there will be a test that includes automation.

  •   wrote:

     

    Wow, would love to try this but it's way way out of my league.  Good luck to the applicants, I hope you do it justice.

    Why not give it a try, Dean?

    • Download and read the manual and datasheet to see what it's capable of.
    • Have a look at previous road tests such as the E36313A Triple Output DC P.S. to see the sort of thing that would be expected when testing a power supply.
    • Make sure you can dedicate the time you think it will require.
    • Don't claim you'll do something that you know you can't deliver.

     

    Unless it's a very specialist piece of equipment, I think that a commitment to do a good job of it is often more important than any particular skills. If you're honest about what you think you can do then the selection process will tell you whether it's "out of your league" or not.

  • 10 Amp and 160Watt. wooww.

    This PSU can deliver good power.image

  • Oh cool, this PSU looks really nice. I like the versatility of the four floating outputs and being able to get to 128V (serial) if needed and I currently can't get anywhere close to 40A (parallel) either! image  It would be nice to compare this to my Keysight E36313A PSU. It's not as pretty and doesn't do all the serial/parallel internally but it looks like a really solid PSU.

  • Oh, it's a HAMEG!

    It's a very nice piece of power! image

  • Another great road-test on the way. It seems R&S are establishing quite a reputation at e14 for themselves by giving away awesome devices.

     

    I must say R&S power supplies are really really good and last a lifetime. I had a chance to use quite a few oldies from them on my job. They are one of the leaders in bench-top power supplies in Germany and very popular among folks. I have seen their power devices hanging around in many labs from 25 or 30 years ago.

     

    Cheers image

  • Wow, would love to try this but it's way way out of my league.  Good luck to the applicants, I hope you do it justice.

  • This is too good to miss out.

  • Another very exciting RoadTest for everyone. Yay! Four floating outputs in one unit really increase the versatility of the unit, the current capability and voltages seem quite wide allowing for most use cases to be met. Using a classic design should mean low ripple and fast response times with better efficiency than a pure linear design. Definitely looks like a classic piece of equipment too - I won't be surprised if this one is built like a tank! I'll definitely have to apply for this one image ... *thinks hard about the application*

     

    It looks like the unit comes with USB/LAN as the default, but the RoadTest seems to show the rear-panel for a GPIB equipped unit. The interface card is "swappable" for other interfaces if necessary.

     

    - Gough

  • What a beast! I've had projects where that 10 A output would have been very useful.

  • Nice power supply. I'm embarrassed to say my current supply was recycled from an obsolete desktop computer. This one has a display, and buttons   .

  • That's an impressively powerful supply! Good to see there is multi-way protection and limits : )
