Description

High-current at low voltage—built for service benches and test stations that power demanding boards without jumping to higher-voltage supplies.

30-Second Fit Check

Need up to 15V with real current headroom: 0–20A (max 300W).
Primary value is low-voltage / high-current stability for boards and fixtures.
Want preset voltage/current + quick output ON/OFF workflow.
Optional comms exist (options vary) if you want basic integration.

What it is + Why it matters

Designed for service/repair environments where current spikes are common.
CC limiting is especially useful at low voltage—set a safe current ceiling before connecting the DUT.
Power display helps catch abnormal draw early (fast triage).

Key Specs

Output: 0–15V, 0–20A
Max power: 300W
Ripple (15V class): ≤10mVrms / ≤10mArms
Accuracy called out: voltage ≤0.1%+2 digits; current ≤0.2%+10 digits

Integration & Controls

Front-panel output ON/OFF and CV/CC indicators.
Optional rear interface: RS485/RS232/USB (options vary); comms are positioned for control/readback.
Chassis size class: 280×130×165mm.

Best for / Not for

Best for: phone/device repair benches, low-voltage high-current boards, production test stations.
Not for: testing 48–60V systems or high-voltage modules—use 60V/100V/150V models.

Typical Applications

Repair/maintenance power for low-voltage electronics
PCB test fixtures with high current demand
Low-voltage burn-in or functional checks (within your process limits)
Bench validation for power rails and converters

Selection Checklist

Define your worst-case current draw—leave margin below 20A.
Use appropriate cable gauge for high current; minimize lead length.
Set current limit first (CC), then enable output.
If you need scripted sequences, consider the 15V 20A P-series model instead.

RFQ Quick Checklist: qty • delivery date • target output range • peak/steady current • comms (Y/N) • fixture/lead constraints.
Note: Final compliance and performance depend on end-product design, wiring, and verification testing.
