2.6 Power Supply (942-200-50, Appendix B)
The UDR power supply is an Astec RBT 45, Kepco KRW351KV, or equivalent. The power supply is rated
at +5 volts @ 3 amps, +15 volts @ 2.0 amps, and -15 volts @ .5 amps. The power supply will operate
from an input voltage from 90VAC to 240 VAC, 47 to 67 Hz. For older units, using the KEC electronics
power supply, the input is user selectable at 115 VAC (92 to 132 VAC) or 230 VAC (180 to 264 VAC).
The power supply is designed to meet safety requirements UL/CSA/VDE. EMI emissions comply with
FCC/VDE requirements.
The power supply provides all internal UDR voltages as well as detector supply voltages. All outputs are
protected with automatic recovery upon removal of overload or short circuit condition.
