TFQ series

Miniature HV power Supply

  • Max Voltage: 1.5 kVdc
  • Max Current: 1 mA
  • Max Power: 1.5 W
  • Wide range of output voltage

Compact PCB mountable high voltage power supplies for photomultiplier

TFQ Series are miniaturized, well regulated high voltage power supplies suitable for photomultiplier. They feature exceptionally low noise, external potentiometer or voltage control and fully protection against continuous output short circuit.

Features and Benefits

  • Ultra low profile design, PCB mountable
  • Low ripple, 3mVp-p
  • Wide range of output voltage (continuous and variable output from 0V)
  • External potentiometer or external voltage
  • Fully protection against continuous short circuit

Applications

  • Photomultiplier Tube (PMT)
  • Geiger Muller Tube (GM Tube)
  • Microchannel Plate/Image Intensifier (MCP/II)
  • Nuclear Instruments
  • Flat Panel Detector (FPD)

Models

Positive polarity output

Model Output Input voltage/Current [typ.] Ripple
Voltage [kVdc] Current [mA] Minimum load* [MΩ] > 5 kHz ≤ 5 kHz
TFQ-1.5P-12 0 to 1.5 1 1 +12 Vdc ±0.5 Vdc,
220 mA
3 mVp-p 5 mVp-p
TFQ-1.5P-15 0 to 1.5 1 1 +15 Vdc ±1 Vdc,
180 mA

Negative polarity output

Model Output Input Current [typ.] Ripple
Voltage [kVdc] Current [mA] Minimum load* [MΩ] > 5 kHz ≤ 5 kHz
TFQ-1.5N-12 0 to 1.5 1 1 +12 Vdc ±0.5 Vdc,
220 mA
3 mVp-p 5 mVp-p
TFQ-1.5N-15 0 to 1.5 1 1 +15 Vdc ±1 Vdc,
180 mA
3 mVp-p 5 mVp-p

Rated output current is not to be drawn at low output voltage range (Output current x Minimum load). Use at larger than minimum load.

Note:
This power supply is designed with adequate consideration for high voltage safety as an integrated power supply.
Yet, please make sure to ground the case for further safety when using.
