ACCHV12V3KV10MAIW 0 to 3kV 10mA HV Power Supply (12V Input)

The ACCHV12V3KV10MAIW is an isolated capacitor charging high voltage power supply. It converts a 12V ± 1V DC input into a regulated output continuously adjustable from 0V to 3kV, delivering up to 10mA. The I suffix denotes 5000V input-to-output isolation and the W suffix denotes lead-wire termination.

Constant-current / constant-voltage (CCCV) operation lets the module charge a capacitor bank at a controlled rate and then hold the bank at the programmed voltage. Typical uses include pulse power systems, energy storage banks, discharge circuits, and piezo actuator drive.

Output voltage is set through the CTRL pin using either a potentiometer or an external 0V to 5V analog signal, with the output linearly proportional to the control voltage. An on-board 5V ± 0.05V reference (5VR) is available for biasing the potentiometer, and the SDN pin provides logic-level shutdown.

The 5000V input-to-output isolation allows the high-voltage return to float with respect to the 12V input ground. This is useful when the capacitor bank shares a ground path with other subsystems, or when the output must be referenced to a potential other than the input ground. Where isolation is not required, the non-isolated ACCHV12V3KV10MAW offers the same electrical ratings at a lower cost.
