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.
  • As for output, polarity of current monitor is negative for P type (+), and positive for N type (-).
  • The offset voltage proportional to output voltage is added to the current monitor. (Approximately 5% to 15% for models 6 kV or less, approximately 25% to 60% for models 10 kV or more)
  • Use voltmeter with input impedance more than 10 MΩ to measure Voltage/Current monitor.

Application note: Example of current monitor correction and amplification circuit

The current monitor of a stabilized power supply is mainly a simplified monitor output to detect a load short circuit, and an offset is added. When measuring the accurate current value, the offset needs to be corrected using a circuit like the following.

P type

P type

N type

  1. Set IM to be 0 V at maximum output voltage and no load. * The input voltage 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

Operations

Connection Diagram

For details, download the datasheet below.

Parallel operation (Increase output current)

Parallel operation (Increase output current)

In some cases, the output voltage of one of the power supplies may not increase, insert a diode in that case.

The reverse withstand voltage of D1 and D2 should be greater than or equal to the output voltage. Only the same model can be used.

Dual tracking operation

Dual tracking operation

The reverse withstand voltage of D3 and D4 should be greater than or equal to the output voltage.

Use a combination of P-type (+) and N-type (-) of the same series and the same output voltage.

Operation Note

  • Do not touch the power supply unit just after turning off it, as high voltage may remain at the output. Before touching it, make sure that the voltage at the output is 0 V.
  • This power supply unit, as an embedded power supply unit, has been designed with due consideration for the safety of high voltage, but for further safety, make sure to ground the Ground (GND) terminal (2) to use.
  • Avoid short-circuiting the load for a long time.
