Description

Built for daily bench work where visibility and quick presets reduce setup time.

30-Second Fit Check

Right range if your DUTs are within 0–30V and 0–5A (up to 150W).
You want a 4-digit display and power readout for quick verification.
Need preset voltage/current (repeatable manual setups).
Optional rear comms exist, but this series is positioned for read/control rather than deep programming.

What it is + Why it matters

A switching DC bench supply aimed at faster troubleshooting—set limits first, then enable output.
CV/CC behavior helps you limit current during short/debug scenarios, reducing accidental overstress.
Power display supports quick “fit check” against expected consumption.

Key Specs

Output: 0–30V, 0–5A
Max power: 150W
Display: 4-digit
Features called out: preset V/I, power display, ON/OFF output
Form factor class: 280×130×165mm

Integration & Controls

Optional rear interface: RS485/RS232/USB (options vary).
Platform notes rear comms are intended for control + readback rather than full programming.
Manual input-voltage switching option appears on the platform.

Best for / Not for

Best for: PCB debugging, small-power module work, electronics experiments that benefit from clear readouts.
Not for: complex automated sequencing—use the programmable P-series if you need list/remote programming.

Typical Applications

Board-level troubleshooting and verification
Low-power device and accessory test
Teaching labs where display clarity matters
Simple production checks with preset limits

Selection Checklist

Confirm you won’t exceed 5A at your target voltage (watch power headroom).
Decide whether you need optional comms for data logging/control.
For sensitive DUTs, plan to set current limit first, then enable output.
Fixture/leads: minimize voltage drop by using appropriate gauge and short runs.

RFQ Quick Checklist: qty • delivery window • typical DUT voltage/current • comms needed (Y/N) • bench constraints.
Note: Final compliance and performance depend on end-product design, wiring, and verification testing.
