1 GENERAL INFORMATION
1.1 DESCRIPTION
This manual contains operation and maintenance instructions covering the Electronic
Measurements, Inc. series of ESKI power supplies. These supplies are constant current
regulated sources of DC power, which also contain boost voltage and ignition pulse to
start Xenon Lamps.
1.2 SPECIFICATIONS
The following specifications describe the operational characteristics of this series of
power supplies. All units are shipped with an AC barrier strip located on the back of the
unit.
AC INPUT: THREE PHASE UNIT
208/220 VAC ± 10% three phase 3 wire delta. 47-63 Hz optional 208/220 VAC ± 10%
single phase 47-63 Hz.
AC INPUT : SINGLE PHASE UNIT
208/220 VAC ± 10% Single Phase 47-63 Hz.
AC INPUT CURRENT: THREE PHASE UNIT
22 Amps per phase for 3 phase power
AC INPUT CURRENT: SINGLE PHASE UNIT
45 Amps
REGULATION:
The current regulation for line variations of ± 10% is .1% over the range of input AC.
The load current regulation for a 25% load change is .1%.
STRIKE VOLTAGE: 25KV
BOOST VOLTAGE: 800 Volts
RIPPLE:
The output ripple measured with the circuit of Fig. 1 will be
≤
0.8V
p-p
at 40 Amps current
output.
EFFICIENCY:
The AC input to the DC output is 92%.
RESPONSE TIME: The programming response time is approximately 1 millisecond for a
50% current change.
STABILITY:
The maximum deviation in output current for an 8 hour period is .05% under conditions of
constant line, load and temperature after a 2 hour warm-up.
