CSS500 SERIES USER MANUAL

December 10, 2012

General Safety Instructions

This is an open type switch mode power supply for use in applications meeting Pollution Degree 2 environment.

A suitable mechanical and fire enclosure must be provided by the end use equipment for shock hazard

protection, fire protection and protection from hazardous energy levels.

READ SAFETY INSTRUCTIONS carefully before working on the unit.

HIGH VOLTAGE WARNING: Dangerous voltages are present in the power supply.

Do not install, test or operate this unit near water and do not spill any liquid on it.

Do not operate this unit unless it is in a secure position.

This unit must be installed and put into service by authorized competent personnel only who are fully conversant

with the hazards of AC line operated equipment and with the particular dangers associated with switch mode

power supplies.

The output power taken from the power supply must not exceed the rating stated on the power supply label.

Refer to typical rating on power supply label for product’s real output.

In case of defect, this unit must be returned to the manufacturer.

Safety Agency Certifications

CSS500-xx, /S, /T versions

These units are approved to UL 60601-1 1st Edition, CSA 601.1-M90, IEC 60601-1:1988+A1+A2 and EN

60601-1:1990+A1+A2. EMC should be evaluated to IEC/EN 60601-1-2 in the final system.

CSS500-xx/I, /SI, /TI versions

These units are approved to UL 60950-1 2nd Edition, CSA 60950-1-07 and EN 60950-1:2006+A11.

Environmental Specifications

Storage and Transportation: -10°C to 85°C, 10% to 95%RH

Operating: 70°C max ambient, IPX0, Continuous, Class I, NOT evaluated as AP/APG equipment.

Input Rating

100-240 VAC, 6-2.5 A, 50/60 Hz

5Vsb (StandBy Output)

The 5Vsb is always “ON”, even when the power supply inhibit is activated. Note that when the supply is

inhibited or is used with convection cooling, the output must be de-rated to 5V 0.25A. The 5Vsb return is via

Common 0V (V-) terminal.

Remote On/Off

The CSS500 can be remotely turned on or off with either an external voltage (Vext) or closed contact.

Output inhibited (OFF) Short pin 2 to pin 3 or 0 < Vext < 0.5V

Output enabled (ON)

Open circuit (floating) or 3.5 < Vext < 5.25V

The Remote On/Off return is via the Common 0V (V-) terminal.

Power Good Signal

An open collector signal indicates if the DC output of the CSS500 is good. An internal pull up resistor is fitted,

tied to the 5Vsb. The maximum sink current is 0.5mA. The Power Good Signal return is via the Common 0V

(V-) terminal.

High = Output good

Low = Output faulty

Fan Fault Signal

An open collector signal indicates if the fan is operating normally. An internal pull up resistor is fitted, tied to the

5Vsb. The maximum sink current is 0.5mA. The Fan Fault Signal return is via the Common 0V (V-) terminal.

High = Fan operating normally

Low = Fan faulty

Fan Connection & Fan Speed Control

The FAN 1 or FAN 2 connectors can be used to power an external 12VDC fan and supply up to 1A. FAN 1

provides a fixed 12V output. FAN 2 provides a variable voltage derived from a sophisticated fan controller

turning on the fan as needed and adjusting its speed according to the cooling requirements.

The FAN 2 speed controller can be over-ridden by applying a jumper on across pins 3 & 5 on CN5.

Current Share (Parallel Operation)

Up to four units may be connected in parallel for either increased output power or for redundant operation and

will share within 10% at full load. For best performance, the output voltages should all be set to the same value.

Connect the current share pins together, and ensure that the output cables to the load are the same wire gauge

and length.

Remote Sense

To compensate for up to 0.25V voltage drop in each of the output cables, connect + sense to + load and –

sense to – load. Twist sense wires together to reduce noise pick up. If remote sense is not used, connect +

sense to V+ and – sense to V–.

Output Potentiometer

The output potentiometer is fitted for factory adjustment only.
