Description
1-22.
OPTION T, PERCENT POWER INDICATOR.
1-23.
The Percent Power Indicator is a 0 to 1 milliampere DC meter scales to indicate 0 to 100 percent
power. The accuracy of the meter is (+2) percent of the full scale deflection. The function of the indicator is to
measure ad display the percent of power supplied to the load. The Percent Power Indicator is used with the
Power Feedback and Current Limit Module (option Q, refer to paragraph 1-20).
1-24.
OPTION W, WATER COOLED HEAT SINKS.
1-25.
The Water Cooled Heat Sinks are recommended when units are to be enclosed in dust-tight
enclosures where a closed-system forced air cooling system is not desired or available. The water cooled
units designated DPAW-1, are physically different from the air cooled units and must be specified at time of
order.
1-26.
ACCESSORY, VOLTAGE INDICATOR.
1-27.
The Voltage Indicator is a 0 to 120 Volt AC Voltmeter. The indicator is connected across the 120 Volt
taps on a transformer in the DPA-1, and the face of the meter is changed at the factory to accommodate the
desired Voltage range. The function of the indicator is to measure and display the RMS output Voltage applied
to the load. The accuracy of the Voltage Indicator is (+5) percent of full scale deflection.
