Switch Mode Power Supply

S8TS

Block-type Switch Mode Power Supply That

Mounts to DIN Rail

• One model covers 30 to 120 W (12-V models).

• One model covers 60 to 240 W (24-V models).

• Easy creation of multi-power supply configurations with different

output power supplies connected together (5-V, 12-V, and 24-V

models).

• Improve power supply system reliability by creating N+1 redun-

dant systems (12-V and 24-V models).

• RoHS-compliant

• Input conditions: 80 to 370 VDC supported for DC input too (EC

Directives and safety standards are not applicable.)

• Operating temperatures to –20°C (24-V models).

Note: 1.

Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal

temperature of the Power Supply may result in ignition or burning.

Refer to page 7 for details on adjusting the output voltage for parallel operation. If set to less than

−10%,

the undervoltage detection function may

operate. Ensure that the output capacity and output current after adjustment do not exceed the rated output capacity and rated output current

respectively. Adjusting V.ADV may cause the output voltage to exceed the voltage range. When adjusting the output voltage, confirm the actual

output voltage from the Power Supply and be sure that the load is not damaged.

Class 2 approval does not apply to parallel operation.

The output current is specified at power output terminals.

Refer to the

Engineering Data

on page 8 for details.

To reset the protection, turn OFF the input power for one minute or longer and then turn it back again.

Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.

The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).

The noise level depends on the wiring method and other factors. Insert one clamp filter (the ZCAT2436-1330A from TDK) as a noise

countermeasure on the input line and ground line combined.

Note: 1.

Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal

temperature of the Power Supply may result in ignition or burning.

If set to less than

−10%,

the undervoltage detection function may operate. Ensure that the output capacity and output current after adjustment do

not exceed the rated output capacity and rated output current respectively. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase

by more than 10% of the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.

The output current is specified at power output terminals.

Refer to the

Engineering Data

on page 8 for details.

To reset the protection, turn OFF the input power for one minute or longer and then turn it back again.

Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.

The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).

Reference Value

Item

Reliability (MTBF)

Value

250,000 hrs min.

Definition

MTBF stands for Mean Time Between Failures, which is calculated according to the probability of acci-

dental device failures, and indicates reliability of devices. Therefore, it does not necessarily represent the

life of the product.

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 ca-

pacitor.

Life expectancy

10 yrs min.
