OWON OEL6030 Programmable DC Electronic Load — 600 V / 30 A / 300 W
OWON OEL6030 programmable DC electronic load: 0–600 V, 0–30 A, 300 W, CC·CV·CR·CP, 5 kHz dynamic mode, 1 mV/0.1 mA readback, remote sensing, SCPI
600 V / 30 A / 300 W precision load, 84 mm wide
The OWON OEL6030 is a single-channel programmable DC electronic load rated at 0–600 V, 0–30 A and 300 W continuous power. It sinks current in four static modes — constant current, constant voltage, constant resistance and constant power — and its CC dynamic mode switches between two programmed levels at up to 5 kHz, which is what you need to see how a supply, battery, charger or DC–DC converter actually behaves when the load steps.
With 1 mV / 0.1 mA readback, four-wire remote sensing, a programmable current slope from 0.01 to 2000 A/ms and full protection (OVP, OCP, OPP, OTP and reverse polarity), the OEL6030 is precise enough for design work and safe enough for a teaching lab. SCPI over USB Type-C, RS232 or RS485 drops it into an automated test sequence — and the whole instrument is only 84 mm wide.
Built to stress what you build
A high-voltage 600 V load with the resolution to see millivolt sag and the speed to slam the current at 2000 A/ms — so your supply, battery or converter meets its spec before your customer finds out it doesn’t.
What the OEL6030 does
Four static modes
CC, CV, CR and CP with a 0.05 Ω–7.5 kΩ resistance range and 10 mW power-setting resolution — plus short-circuit simulation in CC, CV and CR.
5 kHz dynamic mode
Two programmable current levels with T1/T2 timing from 0.1 ms to 50 s and rise/fall slope from 0.01 to 2000 A/ms (min. rise time 20 µs) for transient testing.
Fully protected
Over-power, over-voltage, over-current, over-temperature (85 °C) and reverse-polarity protection guard both the load and your device under test.
SCPI over USB, RS232 & RS485
A front-panel USB Type-C port and rear RS232/RS485 with the SCPI protocol and free Windows software for automated test.
Ideal for
- Design, repair and validation of DC power supplies and adapters — including high-voltage PV strings and telecom rails
- Battery and charger testing at up to 30 A discharge current
- DC–DC converter and solar-cell characterisation
- Education labs and automated production test over SCPI
Test functions
- Static CC / CV / CR / CP loading with 1 mV / 0.1 mA readback
- Dynamic load-transient testing to 5 kHz with programmable slope
- Four-wire remote sensing to cancel test-lead voltage drop
- Optional “T” version: battery-discharge, OCP and OPP routines — “V” version adds ripple test
