We are thrilled to announce our new partnership with Static Power, their product range complements our high-quality AC Power Conversion and Protection range of products for the New Zealand Market. Along with our single & three phase uninterruptible power supplies, power quality products, surge protectors and filters, we can now provide customers with everything they need to protect and ensure high reliability of equipment and systems in sensitive or critical applications.
Static Power is recognised globally for the design and manufacture of it’s brand of Intelligent Static Transfer Switches, or iSTS. Integrated into a UPS or power distribution system, an iSTS device will safeguard your critical equipment and services by automatically and seamlessly switching to an alternative supply.
iSTS transfer Switches are manufactured in AU using rugged solid-state switches with no moving parts, unlike other cheaper automatic transfer switches that use inferior relay switching components. Moving parts in the ATS are susceptible to overheating, contact bonding, coil burning and other failures.
They are available in different formats including: small DIN-rail mounted units, single-phase bypass switches for industrial applications, rack-mounted single and 3 phase static switches for telco, outdoor and data centre applications, wall-mounted and freestanding units in single and 3 phase for protection of whole departments or complete critical infrastructure.
Helios Power Solutions can assist with advice and selection to provide an optimal solution with quality and reliability from the smallest to the highest power demands. Use of the static switches is not limited to data centres, as medical facilities, critical industrial processes, and diversification of supply from two substations can all be achieved through iSTSs.
ATS Automatic Transfer Switch Vs STS Static Transfer Switch
An STS – static transfer switch has no mechanical switching devices (SCRs used for switching) and on manual command, transfers your critical load at the point of zero current in the AC waveform. As such this is at a point where there is no net-flow of power to the load and is, therefore, the best opportunity to undertake the change-over. In case of loss of the primary source, transfer is done at any point in the waveform to avoid any break of supply to the load. Transfer time is 0ms as long as both sources are synchronized. SCRs are liberally rated with large safety margins and power supplies are redundant to ensure long life and reliable operation.
ATS – Automatic Transfer Switch, claim to do this also, however, these do not protect your load under all conditions. Transfer time is typically less than four milliseconds vs zero milliseconds for Solid-State Transfer Switch. The relay types can cause arcing and sparking across the gaps of the contact of the internal relays that are used to undertake the change-over. However, they are typically intended for smaller loads (16-20A) and in principal, switch-mode power supplies in the loads are capable of handling 2-4ms breaks. They also protect the loads from brownouts or overvoltages
IP54 Outdoor & Walled Mount Static Transfer Switches
Static Transfer Switches for Switchboard Manufacturers
Static Transfer Switch for High Power Applications
Other Products Available
Central Static Bypass Switch
The central Static Bypass Switch will operate if one of the UPS fails, avoiding overload of the remaining units and the “cascade” disconnections which would result.
Solid-State Switch & Breaker
Fast, arc-free and fully static, Static Power’s LVAC and LVDC Solid-State Switches and Breakers are commonly used to commute a source and/or to break a fault. Break is quasi-instantaneously, no rest time after break, practically unlimited number of operations.
