Instruction Manual

1 Pin Confi guration

3.1 Wiring input pin

(1) External fuse

¡

The input circuit of CBS Series does not come with a built-in fuse.

In order to protect the power module, a normal-blow fuse should

be installed to +VIN.

¡

When multiple modules get input voltage from a single front-end

power supply, a normal-blow fuse must be installed to each mod-

ule.

(2) Noise Filter/Grounding Capacitor

¡

A grounding capacitor C

Y

must be used to reduce the line noise

on the input line and stabilize the power module operation (Fig.

2.1). Note that resonance and inductance from the input line fi lter

may cause the power module to become unstable.

¡

An appropriate fi lter must be used if conformance to the conduct-

ed noise regulation is required or if surge voltage may be applied

to the unit. Please consult us for more details.

¡

Install a grounding capacitor C

Y

of at least 4700 pF as close to the

input pins as possible (within 50mm of the pins).

2 Connection for

Standard Use

¡

The power module needs input and output connections as shown

in Fig. 2.1.

Reference: 3 ”Wiring Input/Output Pin”

6.5 ”Derating”

¡

Short the following pins to turn on the power module.

-VIN

RC, +VOUT +S, and -VOUT -S

Reference: 4.4 ”Remote ON/OFF”

4.5 ”Remote sensing”

¡

Only DC voltage can be applied to CBS Series. Applying AC volt-

age will damage the power module.

¡

The power module is designed for conduction cooling. Make

sure that heat sinks, fans, etc. are used for heat dissipation.

Refer to 6.5 ”Derating”
