BE2811 – High Stability Current Source ±5A ±18V

The BE2811 module is a non-isolated high performance true current source designed to safely and reliably drive magnet loads up to 1H with excellent noise and stability performances. It is also perfectly suited to drive diodes in burn-in or characterization benches for instance.


The BE2811 is a 2-quadrant current source with transient 4-quadrant operation in order to sink the energy stored in the magnet when stopping the power supply or when applying large current changes.

Like all other ITEST products, this module can be customized to the need, including improved performances. Do not hesitate to contact us. Download the product’s datasheet to get the complete product specification.
