• TWO-YEAR WARRANTY

INPUT VOLTAGE RANGE:
105 to 125 Vrms, 50 to
420 Hz single phase. 

LINE REGULATION:
0.1% or 10mV (whichever is
greater) over entire input range.

LOAD REGULATION:
0.1% or 10mV (whichever is greater) for change from no load to full load.

RIPPLE:
0.02% or 5 mV rms (whichever is greater).

ADJUSTMENT RESOLUTION:
30 mV maximum.

LOAD TRANSIENT RECOVERY TIME:
Output voltage typically returns to regulation limits within 75
microseconds after a 50% step change in load current.

TEMPERATURE RANGE:
Operating: – 4°F (-20°C) to +160°F (+71°C) without
derating, forced air or heat sinking.
Storage: -40o F (-20°C) to +185°F(+85°C).

TEMPERATURE COEFFICIENT:
0.03% per degree Celcius.



ALTITUDE:
10,000 feet above sea level. 

ISOLATION VOLTAGE:
300Vdc between output terminals and chassis ground, 1.5K Vdc input to
output and input to chassis.

INSULATION RESISTANCE:
20Megohms minimum, between input and chassis,
input and output, and output and
chassis when measured at 500 VDC.

POLARITY:
Inputs and outputs are isolated; either
positive or negative side may be grounded.

SHORT CIRCUIT PROTECTION :
Each unit is completely protected against an overload or short
circuit of any duration. The output voltage automatically
restores to normal when the overload is removed.

REMOTE ERROR SENSING:
Each unit contains a means by which the regulator circuit monitors the voltage directly at the load using extra “sensing” leads. The resulting circuit action compensates for a dc voltage drop up to 0.5 volts in the load leads. 

TURN ON / TURN OFF OVERSHOOT:
The output voltage overshoots during “turn on” or “turn off” typically will not exceed 0.1% of the output voltage,
or 20 mV (whichever is greater).

OUTPUT IMPEDANCE:
DC to 1K Hz – 0.003 RL or 0.03 ohms max.*
1K Hz to 10K Hz – 0.008 RL or 0.16 ohms max.*
10K Hz to 100K Hz – 0.015 RL or 0.3 ohms max.*
* whichever is greater
RL = rated load resistance

RELIABILITY:
The mean time between failure

(MTBF) per MIL-HDBK-217C ground benign under worst case operating conditions of full output current, max. input voltage and 50° C ambient is
61,183 hrs for RN15T15.

MOUNTING:
Threaded inserts are provided for
mounting of cases (see case drawings).
