BE2850 – Current Source: ±2A 50V, one output channel

Very low-noise bipolar Magnet or Diode Power supply for the most demanding applications: particle accelerators, reliability test of diodes in series…



This bipolar current source module is the right choice for demanding applications. It can be used as a Magnet power supply (up to 10H) or as power supply for diodes connected in series.

Thanks to ITEST deep expertise in low-noise analog electronics, this power supply offers the best noise performances available on the market: 25ppm peak to peak (10Hz-10kHz).

Exceptional 1.000.000 hours field proven MTBF decreases maintenance costs and suppress the need for redundancy in critical applications, such as particle accelerators.

Several power supplies can be synchronized by different means: hardware trigger input, software trigger, UDP broadcasting.

The best companion to host this module is the BiLT 19” chassis. This 4U-high chassis can be populated with up to 14 current source modules, offering an unrivaled power supply density that will always fit in existing cabinets. The chassis modern and robust Ethernet Controller operates 24/7 for years without fault.

Like all other ITEST products, this module can be customized to the need, including improved performances. Do not hesitate to contact us.
