Description
Overview
The B&K Precision MDL252 is a dual-channel DC electronic load module for testing power sources including AC/DC power supplies, batteries, fuel cells, and photovoltaic arrays. Users can allocate up to 250W per channel with a total combined power of 300W, enabling flexible power distribution between channels. Using DSP technology, the module operates in multiple load modes to simulate realistic and non-linear loading behavior.
Key Features
- Dual-channel design with flexible power allocation: up to 250W per channel, 300W total
- Voltage range: 0 to 500 V, Current range: 0 to 120 A (per channel)
- 16-bit resolution voltage and current measurement (0.1 mV, 0.01 mA precision)
- Transient mode operation up to 25 kHz
- Five load operation modes: CC, CV, CR, CW, CZ
- Synchronous Load on/off and adjustable slew rate in CC mode
- Remote voltage sensing for wire drop compensation
- Parallel operation of identical modules for higher power applications
- Short circuit test capability
- Comprehensive protection: OVP, OCP, OPP, OTP, and reverse voltage
- Standard interfaces: LAN, GPIB, USB, RS-232 with USBTMC/SCPI protocol
Applications
- Simultaneous testing of multiple power rails and output channels
- Multi-output power supply validation and characterization
- Battery management system testing
- Fuel cell and renewable energy source testing
- Automated and production test system integration
