Description
Mid-voltage circuits with real current need headroom. The Keysight E3645A power supply gives you 80 W from one output, with a 35 V range and a 60 V range. Also, Lost in HCM lists it for rental and sale in Vietnam.
Two ranges at 80 W
Keysight lists the ratings below. Also, the power figures come from multiplying the two values, so they show why the unit carries an 80 W rating.
| Range | Maximum current | Power at the corner |
|---|---|---|
| 0 to 35 V | 2.2 A | about 77 W |
| 0 to 60 V | 1.3 A | about 78 W |
As a result, you get close to full power at both ends of each range.
Jobs for the Keysight E3645A power supply
- 24 V industrial controls and PLC input modules.
- 48 V telecom-style rails for bench tests.
- Solenoid valves and relays that need more than a few hundred milliamps.
- Gate-drive and driver stages during power-electronics prototyping.
Ports you can see in the photo
In addition, the rear panel in the product photo shows RS-232, GPIB and a screw-terminal output block. As a result, the unit connects to a test rack as easily as to a bench lead. Keysight also quotes normal-mode ripple and noise under 8 mVpp, which helps when you power analog stages.
Fitting it to your project
First, list the highest voltage your device sees, then its peak current. If the pair lands inside one range, the Keysight E3645A power supply covers it. Next, decide on the schedule. For a three-day check, rent. For a permanent station, a purchase quote makes more sense.
Request the E3645A
First, tell Lost in HCM your dates, delivery city, interface and cable needs, and ask about calibration paperwork. Then request a quote from Lost in HCM for the Keysight E3645A power supply. For official data, open the Keysight E3645A page. Similar units sit under power supply listings, and you can contact SMK Vietnam with any question.
E3645A questions
What are the two ranges?
Keysight lists 0 to 35 V at up to 2.2 A and 0 to 60 V at up to 1.3 A, both from one output.
Is it a dual-output supply?
No. The listing describes one output with dual ranges, so you pick a range rather than a second channel.
Which connections does the rear panel show?
The product photo shows RS-232, GPIB and a screw-terminal output block. Confirm cables with Lost in HCM.
