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 module designed for Photomultiplier Tube (PMT) applications.
Delivering up to 5 W of output power in a compact footprint, the TH series is ideal for driving multiple PMTs or PMT arrays.
The series features ultra-low ripple noise and comprehensive protection against arcs and continuous short circuits.
FEATURES AND BENEFITS
- Compact footprint, PCB mountable design
- Ultra-low ripple: 7 mVp-p (1 kV output model)
- Low noise via 6-sided metal shield case
- High output power (5 W) suitable for PMT arrays
- High stability and precise regulation
- Complete protection circuit (Arc and continuous short-circuit protection)
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 is available when the output voltage is between 50% and 100% of the maximum rated voltage.
- * At output voltages below 50%, the output current must be derated linearly. Ensure the load resistance is sufficient to maintain operation within these limits.
