Static Transfer Switch STS SERIES

Product catalog summary

Overview: The Hannibal microprocessor-controlled Static Transfer Switch (STS) is designed to monitor input sources, ensuring they remain within specified current and frequency limits. It facilitates the transfer of critical loads to the prioritized source, or alternatively to a secondary source if the primary is out of limits.

Key Features:

Microprocessor-based control with thyristor-based switching.
Supports both synchronous (<5 ms transfer time) and asynchronous (<11 ms transfer time) transfers.
Protection features include thermal fuse, overvoltage, and maintenance bypass switch protection.
Front panel with 2x16 LCD and selectable source priority.
Optional third input source and various communication options (RS232, RS485, Modbus RTU, SNMP).

General Specifications:

Fusible surge suppression and bypass line.
Redundant fans with natural cooling and smart fan system.
Ingress protection up to IP66 and customizable cabinet color.
Touch panel with mimic diagram and auxiliary trip contact.
Earth fault and phase voltage/sequence protection.

3 Phase Technical Specifications:

Models range from STS350 to STS3800 with nominal currents from 50A to 800A.
Voltage range: 200-600VAC, 3Ph + N + PE, with a ±15% transfer range.
Efficiency >99% with break-before-make transfer type.
Overload protection and various communication options available.
Environmental conditions: operational temperature 0°C - 50°C, storage -10°C - 70°C, relative humidity <90%.

1 Phase Technical Specifications:

Models range from STS1016 to STS1150 with nominal currents from 16A to 150A.
Voltage range: 110-265VAC, 1Ph + N + PE, with a ±20% transfer range.
Efficiency >99% with break-before-make transfer type.
Overload protection and various communication options available.
Environmental conditions: operational temperature 0°C - 50°C, storage -10°C - 70°C, relative humidity <90%.

Standards and Mechanical Details:

Complies with EN62310-1, EN62310-2, EN62310-3 standards.
Dimensions vary by model, with options for rack-mounted configurations.

Catalog excerpts

We will find a product or make a new one Static Transfer Switch STS SERIES Static Transfer Switch Hannibal microprocessor-controlled static transfer switch constantly monitors the sources connected to the inputs; checks whether they remain within the current and frequency limits and decides if they are synchronized with each other. If the prioritized source is within the determined limits, the critical load is transferred over to the prioritized source. If the prioritized source is not within the determined limits, the load is then transferred to the other source which is within the determined limits.
