PS480D72 Quick Setup Guide
Requirements
• PS480D72 Power Supply
• A at blade screw driver
• A 24V/1A (max) power supply if "DC OK" remote signal is used.
Overview
920-0130C
Before you Start
• The product must be installed, operated, serviced and maintained by qualied personnel in compliance with applicable standards
and regulations.
• Do not open the device, it does not contain replaceable components. The tripping of the internal fuse (if included) is typically
caused by an internal failure.
• Do not repair or modify the device, if a malfunction or failure should occur during operation, send the unit to the factory for
inspection.
• Never carry out work on live parts! Danger of fatal injury! The product’s enclosure may be hot. Allow time for product to cool down
before touching it. Do not allow liquids or foreign objects to enter into the product.
• To avoid sparks, do not connect or disconnect the device before having previously turned-o input power and waiting for internal
capacitors to discharge (minimum 1 minute).
Connection Protection
1. Green LED (output DC OK)
2. Red LED (Overload)
3. Output Voltage Adjustment (70-80VDC)
4. Current Mode selection: SINGLE or
CURRENT SHARE
5. DC output connection (70VDC)
6. DC OK output connection(24VDC)
7. AC Input connection
The device is protected against overload (OL),
short circuit (SC), over-voltage (OV) and over-
temperature (OT).
OL behavior in SINGLE mode: Hiccup Pattern
Max. OL= 1.5 x I nominal. The output voltage
remains constant at nominal voltage for 5s and
after that time the device starts an ON/OFF cycle.
OL behavior in CURRENT SHARE mode:
Maximum output current is limited to 1.1 x I
nominal current. If the load resistance is further
decreased the output voltage starts to drop.
SC behavior in SINGLE mode:
The device supplies 1.5 x I nominal current for 5
sec. After that time, it switches o for 10 sec. The
ON/OFF cycle is repeated continuously.
SC behavior in CURRENT SHARE mode:
The device supplies 1.1 x Output current
continuously into the short circuit without
switching o.
Output OV circuit protection:
The output is protected against potential OV due
to internal malfunction or coming from the load
for V nominal X 1.3.
OT protection:
Turns o the device if the internal temperature
exceeds a safe limit. It will shut down at 100°C
±5°C, and auto-recover at 60°C ±10°C. To
resume normal operation: reduce ambient air
temperature, increase cooling, or reduce load.

To parallel connect more than one
PS480D72 power supply, each device
must be set for current share mode.
