Installation
The PSS160E/C Power Supply can be DIN rail or panel
mounted. The unit is designed to reach a crowbar current
and safely shut itself down when a secondary side short
circuit is encountered. The unit will recover automatically
when the short circuit is removed. For DIN rail mounting,
use the Accessory Catalog No. PSSDIN.
NOTE: WHEN WIRING THE SYSTEM, INSURE ALL
POWER IS REMOVED BEFORE BEGINNING THE
INSTALLATION.
For 48V DC operations, the units can be operated in series
as shown in Figure 1.

Input Wiring Requirements
115V AC or 230V AC Input
The PSS160E is a single-phase input unit. It has a selectable input voltage of 115V AC or 230V AC. To select 115V
AC input you must install the jumper cable (included with
unit) between the 2 VS terminals. To select 230V AC operation, leave jumper off.
To wire, connect the (L) terminal to line voltage, the (N)
terminal to neutral and the center terminal to ground. See
Figure 2.

External Fusing
External fusing is not required. If desired, use the following:
3.5 amp. fuse for 115V AC and 230V AC, 1 amp. fuse for
480V AC.
Voltage Output Adjustment
Vout Adjust — Operator can adjust output voltage 22.5 to
28.5V DC.
Fault Relay Output
Normally Open (NO) and Normally Closed (NC) relay is
energized when power supply is operating under normal
conditions. A fault will trigger the Form “C” contact to deenergize. Contact is rated for 30V DC — 1 amp. or 125V
AC to 1 amp.

Load Sharing Instructions for the PSS160E/C — Maximum 3 Units
1. Power up each unit and measure the output voltage to
make sure that they measure within 2V of each other.
Factory default should be sufficient but if any changes
have been made it is recommended to recheck output
voltage.
2. Wire up the outputs of each supply to a common terminal point. Make sure to keep the wire length from the
output of each supply to the common point as close in
length with one another as possible and, in addition, as
short as possible. This will reduce the load sharing
imbalance. Connect the load sharing terminals of each
supply together in parallel. That is, connect all of the
(+)s together and the (-)s together. The use of a twisted
pair is recommended but not necessary unless the
cabling is longer than 1m (3 ft.) or if there are many
noisy devices in close proximity (i.e., VFDs).
3. Turn on the AC and the units should be sharing the
load. Please note that you require a minimum load of
0.5A per power supply in order that the load sharing
works, otherwise you may get one or more supplies
shutting down. This is not a reason for concern, the
supply(s) that shut down will turn on as soon as the
load requirement increases.
4. The power supply total output should be derated to
85% of typical output since open loop load sharing is
being utilized. You can load share up to 3 units for a
total power output of 408W (16.6A at 24V DC).
