Current range must be chosen to suit the appropriate maximum ambient temperature. Current ratings apply for entire voltage range.
REGULATED VOLTAGE OUTPUT (each output)
Regulation (line) 0.15% for input variations from 105-125, 125-105, 210-250, or
Regulation (load) 0.15% for load variations from no load to full load or full load to no
Ripple and Noise 1.5mV rms, 5mV peak to peak.

OVERSHOOT — No overshoot under conditions of power tum-on,
AC INPUT —105-125 or 210-250 volts AC at 47-440 Hz. Standard LOT-W and LOT-X power supplies are factory wired for 105-125
volt input, but are available factory wired for 210-250 volt input. See Figure 1 and schematic diagram for rewiring of AC input.
Input power*: 175 Watts (LOT-W) 90 watts (LOT-X). Power factor*: 0.8. Ratings apply for 57-63 Hz input. For 47-53 Hz
input derate current 10% for each ambient temperature given in table I. For 63-440 Hz input consult factory.
•With output loaded to full current rating and input voltage 125 volts AC, 60 Hz.
TRACKING (±12 to ±15V output only) — Absolute difference between negative and positive outputs within 2%; 0.2% change for all
conditions of line, load, and temperature.
OVERLOAD PROTECTION — Automatic electronic current limiting circuit, limits output current to a safe value, protecting load and
power supply when overloads and direct shorts occur.
INPUT AND OUTPUT CONNECTIONS - See outline drawing for location.

STORAGE TEMPERATURE - -20°C to +85°C
DC OUTPUT CONTROL — Screwdriver voltage adjust controls permit adjustment of DC output voltages. One control simultane-
ously adjusts the dual (±12 to ±15V) outputs. A separate control is provided for the single, 5V output. See outline drawing
for location of controls.
