Features & benefits

Straightforward operation

All functions can be operated from the front panel; separate rotary knobs for each channel to adjust voltage and current.

Galvanically isolated channels

All channels are galvanically separated and can be combined for higher voltage or current. For each channel you have separate voltage and current displays (4 digits at channel 1+3; 3 digits at channel 2).

Small, compact and quiet

Combination of primary transformer, secondary switching regulator and additional linear control reduces weight and size.

Parallel & serial operating mode

Because all channels are galvanically separated, they can be combined. In the parallel operating mode, channels can be bundled to achieve higher currents. In the serial operating mode, channels can be combined for higher output voltages.
