MINIATURE HIGH VOLTAGE POWER SUPPLY
- Voltage range: 1.5 kV
- Current: 1 mA
- Power: 1.5 W
- Wide range of output voltage
Compact PCB-mountable high-voltage power supplies for photomultiplier tubes
TFQ series, a compact PCB mountable power supply module, provides extremely low ripple 3 mVp-p at 1.5kV output.
With its low-profile design and ultra-low noise characteristics, this compact high-voltage power supply is an ideal choice for Photomultiplier Tubes (PMTs), Microchannel Plates (MCPs), and other precision instruments.
FEATURES AND BENEFITS
- Ultra low profile design, PCB mountable
- Low ripple, 3mVp-p
- Wide range of output voltage (continuous and variable output from 0 V)
- Output voltage control by external potentiometer or external voltage
- Enhanced protection features (Continuous short-circuit protection)
APPLICATIONS
- Photomultiplier Tube (PMT)
- Geiger Muller Tube (GM Tube)
- Microchannel Plate (MCP)/Image Intensifier (I.I.)
- Nuclear Instruments
- Flat Panel Detector (FPD)
Models
Unless otherwise specified, the specifications are defined at the maximum rated output after 30 minutes of warm-up
and apply to output ranges from 10% to 100% of the maximum rating.
| Model | Output | Input voltage/Current [typ.] | Ripple [mVp-p] | |||
|---|---|---|---|---|---|---|

* Rated output current is not to be drawn at low output voltage range (output current × 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.
