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 [kΩ] | Ripple [mVp-p] | Input Voltage [Vdc] | |
|---|---|---|---|---|---|
| Voltage [kVdc] | Current [mA] | ||||
| 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 [kΩ] | Ripple [mVp-p] | Input Voltage [Vdc] | |
|---|---|---|---|---|---|
| Voltage [kVdc] | Current [mA] | ||||
| TFH-2N-12 | 0 to -2 kV | 2 mA | 480 kΩ | 10 mVp-p | 12 V |
| TFH-2P-15 | 15 V | ||||
Add the suffix "-12" for 12 VDC input or "-15" for 15 VDC input to the model number. (e.g., TFH-2P-12)
Ensure that the load resistance is greater than the minimum load resistance specified in the table. The rated output current may not be available at low output voltages due to load resistance limitations.
Specifications
- Input voltage
- 12 Vdc or 15 Vdc
