Main Screen
The “Main Screen” of the Chargemaster VCM displays:
1. Measured Voltage (kV)
2. Lightning bolt symbol “ ” to indicate output is “on”
3. Measured Current (mA)
4. Control Mode: VLT (voltage control) or CUR (current control)
5. Setpoint: Displays voltage/current setpoint or if the unit is in remote operation
6. Key symbol to indicate the keypad is locked
7. HV Output: Displays if HV is on or in remote operation.
8. Status: Displays the status of the unit. If the limit light is on, it will display the
reason or condition for the light.

Operating Modes
Simco-Ion’s Chargemaster VCM Electrostatic Generating Power Supplies can be
run in either Constant Current or Constant Voltage mode. Select the mode that is
best for your application:
1. In the Constant Current mode, the power supply maintains stable and strong
pinning power even as ambient conditions change, or the ionizing electrodes get
contaminated with time, or the material’s properties vary.
2. In the Constant Voltage mode, the power supply provides stable and consistent
pinning voltage, even with varying load impedance. This is the traditional
control mode employed by earlier versions of Simco-Ion Chargemaster power
supplies.
