Low Ripple Power Supply for Photomultiplier Tubes (PMT)
The TFH series is a compact, high-precision PCB-mount high-voltage power supply. Featuring ultra-low ripple and high reliability, this series is ideal for photomultiplier tubes (PMT) and other noise-sensitive applications.
FEATURES AND BENEFITS
- Low ripple of 10 mVp-p
- Low emission noise with 6-sided metal shielding
- Output voltage control via external potentiometer or external control voltage
- Enhanced protection against continuous short circuits
APPLICATIONS
Models
| Model | Output | Minimum load | Ripple | Input Voltage | |
|---|---|---|---|---|---|
| Voltage | Current | ||||
| TFH-2P-12 | 0 to +2 kV | 2 mA | 480 kΩ | 10 mVp-p | 12 V |
| TFH-2P-15 | 15 V | ||||
| Model | Output | Minimum load | Ripple | Input Voltage | |
|---|---|---|---|---|---|
| Voltage | Current | ||||
| TFH-2N-12 | 0 to -2 kV | 2 mA | 480 kΩ | 10 mVp-p | 12 V |
| TFH-2P-15 | 15 V | ||||
* As for 12 Vdc input type, add "12", or for 15 Vdc input type, add "15" to Model No. [Example] TFH-2P-12
note:
Rated output current is not to be drawn at low output voltage range (output current × minimum load). Use at larger than minimum load.
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.
