STS

Lotus Energie Static Transfer Switches

3kVA – 4000kVA & 25A – 600A

Lotus Static Transfer Switch (STS) Power Systems International transfer switches. Designed to provide switching between two independent AC power sources Lotus STS ensure “highest availability”of the power supply to sensitive and critical applications to transfer the energy to another supplier without any interrupts.  The use of static transfer switch and 2N architecture increases the maintainability of the switch panels and upstream equipment.

Usage Areas of STS

Data Centres, Industrial IT Solutions, Single Power Supply Systems, Automatic Transfer Switches

Lotus STS can provide intelligent automatic transfer switches that can be powered from two UPS systems, differentmains supplies or a combination of both. The system also has distribution with compatibility for eight network devices to be connectedfrom its output sockets. Higher reliability levels are achieved by using dual power sources and outlets that can be programmed to schedule individual device shutdowns, or delay priorities ensuring maximum uptime and control for the user.

The front panel has an LCD display providing input & output status, alarms and key measurements information which can also be remotely monitored using RS232, USB or Simple Network Management Protocol (SNMP) communications

Expert Switch Three-Phase is a static exchange switch for modern and IT settings requiring extra security from power deficiencies. Can be utilized related to an UPS or as a different independent gadget. Accessible for both 3 post or 4 shaft establishments. Naturally changes to auxiliary inventory if the essential source falls outside adequate resilience. You can likewise physically move either distantly or from the front control board.

In the event that one of the two info power sources falls outside resistance levels, Master Switch consequently moves to the optional stockpile. This exchanging is immediate if the sources are in-stage, yet regardless of whether they are non-simultaneous the exchange time is under 10 msecs.

Exchanging is likewise conceivable physically through the front board or even distantly.

In case of an overload, you can set the degree of intercession where the MTS’s inner insurance gadgets will hinder the force supply.

What’s more, in outrageous cases like a downstream short out, Master Switch naturally disengages the influenced burden to secure the activity of different burdens.

Completely autonomous, separate circuits supply the MTS’s interior rationale. These are hot-swappable importance you can supplant them, whenever needed, without making an interference the heap. Force Supply Backup usefulness guarantees helper power from an outer source if the two supplies come up short.
