MINIATURE HIGH VOLTAGE POWER SUPPLY MODULES
- Voltage range: 1 to 2 kV
- Current: 2.5 to 5 mA
- Power: 5 W
- Metal Shielded case
Miniature High Voltage Power Supply Modules
The TH series is a compact, well-regulated high voltage power supply designed for Photomultiplier Tube (PMT) applications.
The TH series features a high power output of 5 W in such a compact size and is ideal when connecting multiple PMTs.
The ripple on output is kept very low and fully protected for short-circuits.
FEATURES AND BENEFITS
- Small Footprint, PCB mountable
- Low ripple of 7 mVp-p (for 1 kV output model)
- Low Noise with metal shielded case
- High power 5 W for PMT array
- Well-regulated, high performance
- Full protection circuit (continuous short-circuit protection, etc.)
APPLICATIONS
Models
| Model | Output | Ripple [mVp-p] | |
|---|---|---|---|
| Voltage [kVdc] | Current [mA] * | ||
| TH-1P | 0 to +1 kV | 5 mA | 7 mVp-p |
| TH-1.5P | 0 to +1.5 kV | 3.3 mA | 10 mVp-p |
| TH-2P | 0 to +2 kV | 2.5 mA | 15 mVp-p |
| Model | Output | Ripple [mVp-p] | |
|---|---|---|---|
| Voltage [kVdc] | Current [mA] * | ||
| TH-1N | 0 to -1 kV | 5 mA | 7 mVp-p |
| TH-1.5N | 0 to -1.5 kV | 3.3 mA | 10 mVp-p |
| TH-2N | 0 to -2 kV | 2.5 mA | 15 mVp-p |
- * The rated output current should not be drawn at low output voltage ranges (output current × minimum load). Ensure that the load resistance is greater than the minimum specified.
- * Output voltage range for this output current is 50% to 100% of the maximum output voltage.
The output current must be derated linearly when operating at levels below 50% of the output voltage.
