CAD Library
S8TS Switch Mode Power Supply Datasheet

Features

Industrial use, modular power supply for multiple configurations

The S8TS is an expandable power supply; standard units can easily be snapped together in parallel to provide you with ultimate flexibility. Expandable up to 4 units, it can deliver a total power of 240W at 24VDC or a multi-output configuration.

Improves system reliability by building up N+1 redundancy
Standard unit; 60 W at 24 VDC, 30 W at 12 VDC and 25 W at 5 VDC
Battery back-up unit protects against power outage
Buffer unit protects against power glitches and outage
EMI Class B, UL Class 2, UL Class 1 division 2

Additional units

S8T-DCBU-01

The S8T-DCBU-01 battery backup block supplies 24 VDC for a fixed period of time during AC input outages to considerably improve system reliability.

S8T-DCBU-02

Prevents equipment stoppage, data loss and other problems resulting from momentary power failures. One S8T-DCBU-02 buffer block provides a back-up time of 500 ms at an output current of 2.5 A. Can be wired to the 24 VDC output from any switch mode power supply.

S8VK-R

When the S8VK-R is used with switching power supplies, it provides a backup system for critical applications that require absolute reliability and zero downtime.

S8M

The S8M turns your machine directly into UL Class 2 compliant, maximum tripping current is 3,8A per channel (adjustable). This unit controls up to 4 circuits. On top of this you will get startup / shutdown –sequence control, display and alarm functions, like voltage, output current, runtime, and over temperature and external reset. These functions can be set by using the front buttons or with the free support tool software. These settings can be protected.
