Description
Overview
The B&K Precision MDL4U400 is a modular, programmable DC electronic load module rated for 80V, 60A, and 400W. It operates in constant current, constant voltage, constant resistance, constant power, and constant impedance modes to simulate realistic loading behavior for testing multi-output power supplies, batteries, fuel cells, and photovoltaic arrays.
Key Features
- 80V/60A/400W single-channel module with bright VFD display
- Five operating modes: CC, CV, CR, CW, and CZ (with DSP-based load simulation)
- Transient mode up to 25 kHz with adjustable slew rate in CC mode
- Standard LAN, GPIB, USB, and RS232 interfaces with USBTMC/SCPI protocol support
- 16-bit resolution voltage and current measurement (0.1 mV, 0.01 mA)
- Remote voltage sensing and synchronous load on/off function
- OVP/OCP/OPP/OTP and reverse voltage protection
- 4U height form factor with certificate of calibration
Applications
- Testing multi-output AC/DC power supplies
- Battery and fuel cell evaluation
- Photovoltaic array characterization
