The AHVAPN2000V20MA is an electronic module for amplifying an analog input voltage into a high voltage output.  It comes with a high voltage DC-DC converter, which converts the 24V input voltage into two output voltages: −2100V and +2100V. The analog input voltage, VIN(t), can be from −10V to +10V, the corresponding output voltage, HVO(t), is from −2000V to +2000V. There are three LEDs indicating: 24V power supply is present and within an appropriate window: 23V to 25V, the high voltage power supply is outputting ±1900V outputs properly, and the control loop works properly, i.e. HVO(t)=180×VIN(t).
