HIGH VOLTAGE
MODULE
SPECIFICATIONS
Input Voltage:
12Vdc for 4W, 24Vdc for 15W and 30W
Nominal Voltage Range:
11Vdc to 30Vdc for 4W, 23Vdc to 30Vdc for 15W and 30W
4W units can operate at 24Vdc input with no
deratings or damage to unit
Input Current:
(typical)
Disabled:
10mA @ 24Vdc
Full output, no load: 160mA @ 24Vdc, 300mA @ 12Vdc
Full output, full load:
4 watt units:
330mA @ 24Vdc, 640mA @ 12Vdc
15 watt units: 850mA @ 24Vdc
30 watt units: 1590mA @ 24Vdc
Voltage Regulation:
Line: <0.01%
Load: <0.01%
Current Regulation:
Line: <0.01%
Load: <0.01%
Stability:
0.01% per 8 hours, 0.02% per day after 30 min. warmup
Accuracy:
2% on all programming and monitoring, except I Sense 10%
Temperature Coefficient:
(typical)
Standard: 100ppm/°C
Optional: 25ppm/°C (T Option)
Environmental:
Temperature Range:
Operating: -40°C to 65°C case temperature
Storage: -55°C to 105°C, non operational
Humidity:
10% to 90%, non-condensing.
Cooling:
Convection cooled, typical. 30 watt units operating at full power might
require additional cooling to maintain case temperature below 65°C.
Methods may include: forced air cooling, use of heat sink or metal
case, etc. It is the user’s responsibility to maintain the case temperature
below 65°C. Damage to the power supply due to inadequate cooling is
considered misuse and repairs will not be covered under warranty.
