Engineering Data

Overload Protection

The load and the Power Supply are automatically protected from

overcurrent damage by this function. Overload protection is activated

if the output current rises above 105 to 160% of the rated current.

When the output current returns within the rated range overload

protection is automatically cleared.

Note: 1. Internal parts may occasionally deteriorate or be damaged

if a short-circuited or overcurrent state continues during

operation.

2. Internal parts may possibly deteriorate or be damaged if the

Power Supply is used for applications with frequent inrush

current or overloading at the load end. Do not use the Power

Supply for such applications.

Overvoltage Protection

Consider the possibility of an overvoltage and design the system so

that the load will not be subjected to an excessive voltage even if the

feedback circuit in the Power Supply fails.

If an excessive voltage that is 120% of the rated voltage or more is

output, the output voltage is shut OFF.

Reset the input power by turning it OFF for at least three minutes and

then turning it back ON again.

Overheating Protection (300 W and 600 W)

If the internal temperature of the Power Supply rises excessively as a

result of fan failure or any other reason, the overheat protection circuit

will be triggered to shut OFF the output voltage.

To restore operation, turn OFF the input power supply long enough

for the Power Supply to cool sufficiently and then turn it ON again.

Remote Control Function (Only Remote control)

This function is to turn ON/OFF the output by applying a voltage to the

remote control connector from a DC power Supply (external power

supply) other than this Power Supply.

Connectors used:

Applicable crimp tool: YC-110R (J.S.T. Mfg. Co., Ltd.) or

YRS-110 (J.S.T. Mfg. Co., Ltd.)

Note: 1. When the external power supply is 4.5 to 12.5 V, the current

limiting resistor R is not required. When it is 12.5 to 24.5 V,

insert 1.5 k

Ω as the current limiting resistor R.

2. Reverse connection of the connector may cause damage

on the internal parts.

3. The +RC and -RC terminals are the secondary circuit of the

Power Supply. Use an SELV output power supply for an

external power supply. The remote control circuit is

insulated from the secondary output of the Power Supply

(functional insulation).

Definition

MTBF stands for Mean Time Between

Failures, which is calculated according to the

probability of accidental device failures, and

indicates reliability of devices.

Therefore, it does not necessarily represent a

life of the product.

Life expectancy

10 yrs. Min.

Definition

The life expectancy indicates average

operating hours under the ambient

temperature of 40°C and a load rate of 50%.

Normally this is determined by the life

expectancy of the built-in aluminum electrolytic

capacitor.
