DC Electronic Loads
Programmable DC electronic loads with CC, CV, CR and CP modes plus dynamic testing — for power-supply, battery and charger validation.
Professional OWON dc electronic loads category introduction
OwonTechnology.eu supplies genuine OWON dc electronic loads for European customers, with EU shipping, manufacturer warranty and local support. Main ranges include OEL85 Series, OEL15 / 30 / 60 Series. Choose by the required technical range, application, connectivity and measurement accuracy.
- Power-supply validation: Any OWON electronic load characterises a DC supply under CC, CV, CR and CP modes — the OEL15/30/60 is cost-effective for general bench testing; choose the OEL85 for faster transient response.
- Battery testing: Choose the OEL85 for battery discharge and internal-resistance measurement — its 0.01 A/ms transient slope handles the dynamic demands of battery characterisation and cycle testing.
- High-voltage testing: The OEL6015/6020/6030 and OEL8511C/8512C models accept up to 600 V input — correct for testing high-voltage power supplies, converters and PV inverter outputs.
- Dynamic / transient testing: The OEL85 series is the right choice when the load must switch rapidly — 0.01 A/ms slope enables full transient-response characterisation of power supplies and DC–DC converters.
DC Electronic Loads from OWON
OWON programmable DC electronic loads sink power under constant-current (CC), constant-voltage (CV), constant-resistance (CR) and constant-power (CP) modes, with dynamic transient testing for characterising power supplies, batteries, chargers and DC–DC converters. All models include over-voltage, over-current, over-power and over-temperature protection with accurate voltage and current readback.
Two series cover the full application range. The OEL15/30/60 series delivers 150–300 W across 150 V, 300 V and 600 V voltage variants — nine models for cost-effective bench testing of power adapters, chargers and converters. The OEL85 series steps up to 200–500 W with a 0.01 A/ms dynamic transient slope, battery internal-resistance measurement and solar-cell characterisation, making it the right choice for demanding validation and production test.

Questions about OWON DC Electronic Loads
Technical selection guidance for choosing the right instrument family and model.
What is the difference between the OEL85 and OEL15/30/60 series?
The OEL85 series (200–500 W) targets demanding validation and production test: it offers a faster 0.01 A/ms transient slope, battery internal-resistance measurement and solar-cell (PV) characterisation modes. The OEL15/30/60 series (150–300 W) is a cost-effective bench load suited to power-supply testing, charger validation and education — nine models across 150 V, 300 V and 600 V voltage ranges.
Which OEL model should I choose for 600 V input testing?
Choose the OEL6015, OEL6020 or OEL6030 (OEL15/30/60 series) for 600 V bench loads up to 300 W. For higher power at 600 V with dynamic testing, the OEL8511C or OEL8512C (OEL85 series) handle 200–400 W at up to 600 V with the faster transient slope.
Can OWON electronic loads measure battery internal resistance?
Yes — the OEL85 series includes a battery internal-resistance (IR) measurement mode. This makes it suitable for battery capacity testing, state-of-health assessment and discharge characterisation without a separate instrument.
Do OWON electronic loads support PC remote control?
All OEL models support remote control and data logging via USB (virtual COM). This allows full control from a PC using SCPI commands — useful for automated test sequences, logging discharge curves and integrating the load into a test system.
