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.
