N39436-60-15 (360W/60V/15A) is recommended. It is a wide range four-channel DC power supply with dual LAN ports.

1) Reduces space occupation.

2) Saves purchase cost.

3) Shortens test time.

4) Enhances test safety.

5) Provides repeatable test results.

The programmable electronic load can be used to test fuel cells, power supplies, DC-DC converters, batteries, chargers, adapters, automobile wiring harness, automobile connectors, etc.

A DC electronic load is an instrument that consumes electrical energy by controlling the internal power or the conductance of transistor and relying on the power dissipation of power tube.

In constant voltage mode, the power supply operates as a voltage source which keeps the voltage constant while output current changes, according to different load conditions.

Line regulation is defined as the ability of the power supply to provide a stable output voltage when the input voltage changes.

In constant current mode, the power supply operates as a current source which keeps the current constant while output voltage changes, according to different load conditions.

Battery simulator is a programmable electronic equipment which emulates the properties of real batteries. The simulator provides voltage, current and power required in the same way as a true battery. 

Load regulation is the ability to maintain a stable output voltage of the power supply despite changes in the supply's load.

Linear power supplies take an AC input, step down the voltage via a transformer, then rectify and filter the input into a direct current output.

Switching power supplies take an AC input, but rectifies and filters into DC first.  Next this DC power is switched to a higher frequency through a switching circuit. It steps down the voltage with a transformer, then is rectified and filtered into a DC output.
