High efficiency
2100 V/100 μA output ranges
Available with positive or negative polarity
Compact package: 29x54x16 mm3 (WxLxH)
The A7502 is a high efficiency, low noise single channel High Voltage DC/DC converters in a PCB mount form factor. It provides a programmable and monitorable output voltage ranging from 0 to 2100 V, when supplied with a +5 V input. It is available with either positive or negative output voltage. The output voltage is regulated by providing a 0 to +2.5 V external voltage (Vset). The maximum output current is 100 µA, regulated by providing 0 to +2.5 V external voltage (Iset). 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.
Thanks to its excellent stability and special design, A7502 power supply is engineered to work in harsh environment and under severe temperature variations.
The module is engineered on a FR4 PCB, coated and housed in DC01 steel box. CAD Altium library components and 3D step models are available on request.
Safety Features Include:
Overcurrent detection if the channel attempts to draw a current larger than Iset, the output voltage is varied to keep the current below Iset limit. The channel behaves like a current generator.
