H SERIES AC/DC
Power-One’s H Series of AC/DC power supplies provides a full
range of features and options for chassis mount applications or 19”
rack systems. With a universal input from 85 to 255 VAC, the H
series meets the most rigorous requirements of commercial,
industrial, and datacom systems. LED indicators display the status
of the converter and allow visual monitoring of the system.
Rated for use in convection applications, the H Series delivers
high reliability power with a Mean Time Between Failure (MTBF)
in excess of 300,000 hours. In addition to UL, CUL, and LGA
regulatory compliance to IEC950/EN60950, the H series displays
the CE Mark.

Input and/or V1 output monitoring circuitry. The input and/or output undervoltage monitoring circuit operates
independently of the built-in input undervoltage lock-out circuit. A logic "low" (JFET output) or "high" signal
(NPN output) is generated at pin 5 as soon as one of the monitored voltages drops below the preselected
threshold level. Consult factory for specific types. Not compatible with -V options.
This option defines an undervoltage monitoring circuit for the input voltage. Equivalent to -D option and
generates an ACFAIL signal (V signal) which conforms to the VME standard. Not compatible with -D option.

H SERIES AC/DC
OUTPUT VOLTAGE ADJUSTMENT
As a standard feature, single output modules offer an adjustable output voltage, identified by the letter “R” in the part number. The output voltage V1 can either be adjusted
with an external voltage (Vext) or with an external resistor (R1 or R2) to the new value, V1
A
. The adjustment range of V1
A
is approximately 0% to 110% of the nominal
output voltage, V1. For output voltages above the nominal output value, the minimum input voltage must be increased proportionally to the increase in output. For example,
to increase the output of an H Series power supply to 110% of initial value, the minimum input voltage must be increased by an additional 10%.
Method 1:
Adjust output voltage V1
A
from 0% to 110% of V1 using Vext between +VOLTAGE ADJUST (pin 14) and -VOLTAGE ADJUST (pin 17). NOTE: Values of Vext must be
between 0.0V and 8.0V.

NOTES:
To prevent damage, R2 should never be less than 47k . R inputs of n units with paralleled outputs may be paralleled,
but if one single external resistor is to be used, its value should be R1/n, or R2/n respectively.
