• Model	Max rating			Slew rate
  	Voltage	Current	Power
  LN-300A-G7	120V	60A	300W	20A / us
  LN-300C-G7	500V	12A	300W	1A / us

Lower voltage operation
There is no operating limitation by Loading Voltage since this series sink load current as far as voltage difference exists.

Parallel operation (Booster function)
Up to 5 sets of Load Station series can be paralleled to expand loading power. It can configure max. 10kW load (LN-1000A X 10 sets). Different power modes can also be paralleled as far as they are same voltage rating.

Ripple & Noise measurement
With optional Ripple & Noise measurement function, it can configure as a power supply tester for power supply testing application.

Sequence function
Max. 1024 steps of sequence operation is possible from PC for various loading. Complicated loading condition can be simulated.

The Load Station series is equipped with various features suitable for evaluation and inspection applications.
External control mode (0 – 10V) can control load current externally, Current monitor for load current monitoring (not isolated), GPIB as well as USB interface.

Low inductance loading cable : Low-L Cable (Option)
The cables designed for low inductance. With this cable, voltage drop may be minimized. 50cm, 100cm and 200cm possible.
