1 Ch 1100 V/1000 µA High Efficiency HV Power Supply Module


  • High efficiency
  • 1100 V/1000 µA output ranges
  • Available with positive or negative polarity
  • Stand alone architecture
  • Compact package: 29x54x16 mm3 (WxLxH)


The A7511 is a high efficiency power supply providing a programmable and monitorable output voltage ranging from 0 to 1100 V, when supplied with a +12 V input. It is available with either positive or negative output voltage.

The board is provided with an over-current protection: if a current larger than the Iout maximum value is drawn, the module is not being damaged.

The output voltage is regulated by providing a 0 to +2 V external voltage (Vset). The module is engineered on a FR4 PCB, coated and housed in DC01 box.
