OWON OEL1515 0-150V 0-15A DC Electronics Load
The OWON OEL1515 is a 150 W programmable DC electronic load offering up to 150 V / 15 A operation. It supports CC, CV, CR, and CP modes with 1 mV / 0.1 mA resolution for precise power testing. Ideal for evaluating power supplies, chargers, and batteries.
The OWON OEL1515 is a compact, single-channel programmable DC electronic load designed for testing power supplies, batteries, chargers, and other DC sources. With a power rating of 150W, voltage range up to 150V, and current range up to 15A, it provides precise and reliable performance for both R&D and production applications.
Featuring four operating modes—Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP)—the OEL1515 offers high flexibility for various test scenarios. Its 1mV / 0.1mA resolution ensures fine measurement accuracy, while built-in OVP, OCP, OPP, and OTP protections safeguard both the load and the device under test.
The unit supports USB, RS232, and RS485 communication interfaces, enabling easy integration with PC control software for remote operation and automated testing. Additional functions include dynamic mode, short-circuit simulation, VON setting, and remote sense compensation for accurate voltage measurement at the DUT terminals.
