LOW RIPPLE POWER SUPPLY FOR PHOTOMULTIPLIER TUBE (PMT)
- Max Voltage: 2kVdc
- Max Current: 2mA
- Max Power: 4W
- Short Circuit Protection
Low Ripple Power Supplies for Photomultiplier Tube (PMT)
TFH Series is a compact, ultra-low ripple, and well-regulated high voltage power supply suitable for OEM or laboratory applications. Electrostatic shielding is provided through 6-sided shielding. With arc and continuous short circuit protection for safe and reliable operation.
FEATURES AND BENEFITS
- Low ripple of 10 mVp-p
- Low emission noise due to 6-sided shielding
- External potentiometer or external control voltage programming
- Enhanced protection circuit (continuous short-circuit is possible)
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 | ||||
* As for 12 Vdc input type, add "12", or for 15 Vdc input type, add "15" to Model No. <Example> TFH-2P-12
* Rated output current is not to be drawn at a low output voltage range (output current × minimum load). Use a larger than minimum load.
