mPD-501 DC electronic load mainly focuses on the testing of power circuit on PCB. mPD-501 offers a solution for function test of Switch step up, Stepdown, Regulators and Driver ICs . Engineer can put components such as CPU, DSP, FPGA; etc on a PCB after the power circuit has been tested. It's not complete to use a meter to measure the voltage. mPD-501 offers engineer OVP, OCP and OPP functions that help engineer know the value of overload current.

On the other hand, engineers can use a programmable DC power supply (mPP series) to offer external power and connect PCB's output to mPD-501. This helps figure out the efficiency of power circuit and check if inductances, capacitances and resistances perfectly work with the power circuit.

mPD-501 not only offers loading emulation of current but also provides OVP and OPP. User can use these functions to test solar power battery, rechargeable battery and motor driver.
