Overview

STS 2000 (32 – 120 A) Single Phase Static Transfer Switch

Deltron STS, allows instantaneous transfer of power sources to the load. If one power source fails, the STS switches to the back-up power source so fast that the load never recognizes the transfer made.

STS 2000 1 phase, 2 pole static transfer switch transfers uninterruptedly critical loads to either of two independent AC power lines. The system monitors two AC inputs. If any of them goes out of the specified tolerance, it transfers the critical load to the other. By increasing the energy quality of the systems used with STS 2000, while reducing the effects of interference and short interruptions, a backup power system is gained.

Compact and Rack Type Design

2U / 3U 19" rack chassis with clip-on rear terminals and optional hot-swap frame.

Microprocessor Control

Full digital control with digitally set points, programmable synchronized and unsynchronized transfers.

Hot-Swappable

Optional hot-swap version for maintenance without interrupting the load.
