Output Monitor

Output value of Voltage (option)/Current monitor

  • Polarity of V monitor is same as that of HV output.
  • Input current increase by 10 % to 20 % when V monitor (option) is added.
  • Polarity of current monitor is negative for P type (+), and positive for N type (-).
  • Current monitor output has offset voltage proportional to output voltage.
  • Use voltmeter with input impedance more than 10 MΩ to measure Voltage/Current monitor.

Application note: Compensation and amplification circuit of current monitor

Current monitor of S series is a simple monitor mainly for detecting output short circuit and has offset voltage.
Voltage monitor is just buffer AMP. Circuit of current monitor deduct current over voltage detecting resistor inside.

  1. At maximum output voltage, set IM to be 0 V without load. *Power supply of OP-AMP is ±15 V.
  2. Place resistors so that meter become full scale at rated output. (not required when using digital meter)

Options

-LW: Slow start

-L2: Voltage Monitor Output

  • up to 6 kV: 1 V/@1 kV
  • 10 k to 30 kV: 1 V/@10 kV

Accuracy ±2.5% F.S.

Operations

Connection Diagram

For details, download the datasheet below.

Parallel operation (Increase output current)

Parallel operation (Increase output current)

  • Put diodes, otherwise output of either unit will not increase.
  • Inverse dielectric voltage of D1, D2 shall be more than output voltage.
  • Connect P type (+) an N type (-) of same series

Dual tracking operation

Dual tracking operation

  • Inverse dielectric voltage of D3, D4 shall be more than output voltage.
  • Connect P type (+) an N type (-) of same series.

Operation Note

  • Do not touch the HV output cable right after turning off the power supply because there might be residue voltage. Make sure the voltage is OV before touching the output.
  • Make sure to ground the GND terminal, pin (2), for extra safety, although this series is designed width various safety features as built-in type HV module.
  • Avoid continuous short circuit
