Rohde & Schwarz HMP4030 Supply, 3 Channels, 384 W, 10 A per Channel

Description

Some loads care more about amps than about volts. The Rohde & Schwarz HMP4030 supply is a three-channel bench unit built for that kind of work, with 10 A available on each output. It shares 384 W across the three rails. Lost in HCM lists it for rental and sale, and it arranges service on request.

At a glance

Where 10 A per channel helps

Higher current opens up jobs that a small supply would trip on. Development benches and industrial electronics tests often fall into that group. For example, a driver board or a power stage may draw a steady load plus a sharp startup surge.

• Bench work on industrial controllers and I/O boards.
• Powering a power stage while you tune its protection.
• Feeding three subsystems from one box during integration.
• Soak tests that need steady current for hours.

Reading the 384 W ceiling

On the Rohde & Schwarz HMP4030 supply, each channel can reach 160 W, yet the instrument tops out at 384 W. Two channels at full power use 320 W. That leaves only 64 W for the third rail. Likewise, 32 V and 10 A on one channel would ask for 320 W, which is twice the channel limit.

So check both numbers for every setup. Then leave some room for surges, because the ratings do not apply at the same time.

A short checklist for the first run

With the Rohde & Schwarz HMP4030 supply, pick leads that suit the current, because thin wire heats up fast at 10 A. Check polarity with the outputs disabled. Then set the protection levels for your device before you switch anything on. Finally, note the serial number and firmware with your results.

Remote sensing can correct for drop in the load leads, and EasyArb plays programmed output patterns. Automation needs the matching optional interface, so confirm the installed module first.

Order the Rohde & Schwarz HMP4030 supply

A project with a fixed end date suits a rental, while a lab with daily demand may buy. Lost in HCM supplies the unit and gives the quote, and SMK Vietnam only shows the listing. Tell the team about your load, your dates and your delivery site. Then request a quote from Lost in HCM. You can also open the power supply listings, read about Rohde & Schwarz or contact SMK Vietnam.

HMP4030 questions

How much current can one channel give?

Each channel is rated for 10 A and 160 W, so the voltage you set decides how much of that you can use.

Can one channel use all 384 W?

No. A single channel stops at 160 W, and the 384 W figure is shared across all three.

Can I automate it from a computer?

Only with the matching optional interface. Ask Lost in HCM which module the unit carries.
