Description

Technical Parameters

GE STS-230-100-2-RM is a GE Digital Energy Static Transfer Switch (STS) designed to switch between independent AC power sources in applications where power supply continuity is critical. The unit is intended to transfer a connected load from one source to an alternative source when operating conditions require a change of supply.

The GE STS-230-100-2-RM is relevant to critical power distribution installations serving industrial facilities, electrical infrastructure and sensitive electronic loads. Before ordering, buyers should verify the rated voltage, current, pole configuration, connection arrangement, and other nameplate details against their existing equipment and installation requirements.

The basic applications of STS STS-230-100-2 RM are in automatic systems for the power industry, power supply systems for the petrochemical industry, computer and telecommunication centers, automatic and security systems of 'intelligent' buildings, as well as other equipment that is highly sensitive to supply interruption. Its high overload capacity and transfer algorithm enable rapid fuse blowing during short circuits. As a consequence, voltage immediately returns to its normal value to supply other loads. The built-in transient voltage surge suppression system for SCR switches provides additional protection against damage to supplied devices.

STS-230-100-2 RM Standard features: Digital Energyô Static Transfer Switch

• Ability to create systems with redundancy (switching between independent electrical supply lines, various UPS devices, and generators)

• Short transfer time (typically 3 ms after line failure)

• Elimination of voltage swells, sags, and interruptions on loads (switch-over)

• Protection against voltage variations out of range

• Switches are controlled by Fail-Safe CMOS Logic

• Internal redundancy for power supply systems and SCR drivers (eliminating failures in single points)

• Easy to install and operate

• Low MTTR (mean time to repair)

• Bypass switches to provide continuous non-break operation during STS maintenance

• Remote switching of power sources

• Status indication of the power supply system and STS

STS-230-100-2 RM Operating modes:

Static Transfer Switches are designed for operation in three modes: preferred source mode – selected preferred source supplies the load. The load is transferred to the other source if the voltage of the preferred source is beyond the acceptable range. Automatic retransferring mode – after transfer triggered by disturbances in the preferred line, the load is transferred to the preferred line again with a delay which is set by dip switches, only if the preferred line is healthy. Manual mode – connections are set manually (not automatically).

Principle of operation：

STS-230-100-2 RM Static Transfer Switch consists of two bi-directional thyristor switches (2 for each phase) equipped with a control and protection system. The 4-pole models have an additional neutral line switch. The control system is based on fail-safe CMOS logic. The input source and output line are protected by transient voltage surge suppression varistors. After failure of the preferred source, the STS checks the state of the alternate power source and transfers the load to the source that provides power of better quality. Many modes of operation and many additional settings are provided to meet site-specific requirements.

Transfer may be triggered by:

• Disturbance of preferred source voltage • Overcurrent in source • Manual change of preferred source • Remote change of preferred source

Transfer is not allowed in the event of:

• Incorrect voltage in the alternate source • Excess output current (in load dedicated STS installation)

Transfer is delayed in the event of:

• No synchronization between preferred and alternate source • Exceeding the phase shift limit between the two sources.

With both sources correct and synchronized (phase error within the acceptable range), manual or remote transfer is performed in less than 200 µs. Transfers initiated by fault conditions on the preferred source depend on the status of the alternate source. For synchronized power sources with a phase error within the limits, switching to an alternate source is obtained within 6 6-ms delay. Lack of synchronization causes a delay before transfer. It is possible to set the delay time with dip switches (11 ms, 15 ms, 23 ms, or 48 ms). The total transfer time is equal to the sum of 2 ms detection time and the alternate source thyristor delay time (so 13, 17, 2,5, or 50 ms respectively).

Compatible Systems and Typical Applications

The GE STS-230-100-2-RM should be described as a power transfer device, rather than a PLC or DCS controller module.

Typical application areas for the STS product category include:

Industrial power distribution: Transfer between independent AC supplies serving critical electrical loads.

Data and communication facilities: Power continuity arrangements for sensitive electronic equipment.

Petrochemical and process facilities: Critical power distribution supporting selected control and auxiliary loads.

Building electrical infrastructure: Dual-source power supply arrangements for designated loads.

UPS-supported installations: Transfer between alternative supplies where voltage, current, source characteristics, and installation design are compatible.

These are application categories, not a guarantee that every installation is compatible with this specific model.

Before replacement, confirm the existing equipment's voltage, rated current, number of poles, wiring arrangement, source synchronization requirements, protection coordination, and mounting dimensions. Do not assume direct integration with GE Mark V, Mark VI, or Mark VIe turbine control systems simply because this product appears in the GE category of the website.

Frequently Asked Questions

What is the rated voltage of this model?

The STS-230 family is associated with the 230 V voltage class. The exact rated voltage and permitted input range of the 100 A model should be verified against its nameplate and applicable documentation.

What is the transfer time?

Transfer time depends on the model, source conditions, synchronization, and configured operating parameters. Request the applicable technical specification if a maximum transfer time is required for the project.

Is it compatible with GE Mark V, Mark V, or Mark VIe?

The product is a power transfer device, not a direct replacement for a Mark-series controller module. Any installation-level compatibility must be established from the electrical design and system documentation.

Are the STS-230-25, STS-230-40 and STS-230-63 interchangeable with the 100 A version?

They are related STS-230 family models, but they have different current ratings. They should not be treated as direct replacements without an approved engineering assessment.
