UPS Configurator

1-phase output

Unit
Sum up the actual consumed power of all connected loads in watts. You can find this information on the power supply of each device.
VA stands for volt amperes and describes a value for establishing the dimensions of cables and cut-outs.
%
If you plan to extend the loads in the near future you can add a power reserve here. It will be taken into account for the power dimensions of tSE UPS but not for the autonomy time.
Redundancy
The power part of tSE UPS design will be calculated with redundancy to minimize the risk of a UPS fault. This is recommended for very critical applications. The autonomy time is not calculated for a UPS failure and will be lower in this case than calculated.

Form:
Select rack-mount UPS to consolidate as much hardware as possible in a 19” rack cabinet. The decision between free-standing tower UPS and rack mounted UPS is mainly a matter of data center design philosophy.
Technology:
Overview about which UPS topology protects against the different mains failures.
Connectors:
Accessories:
SNMP adapters are communication extensions that control and monitor UPS devices via network or web.
The external bypass switch is used to disconnect tSE UPS for maintenance work allowing uninterrupted, continuous feed of the connected loads. It also enables a UPS test run.
It provides potential-free contacts at the outputs, which can be configured optionally as N O or N C contacts and which can be used as binary input for the SPS or building control systems.
The distribution bars enables you to distribute tSE UPS outputs among several loads. Different versions support the load connection via Schuko and/or IEC 60320.
Sensors play an important role in process automation. They detect external events and conditions, and signal them to tSE UPS.
The panel enables parallel operation to increase power and/or to achieve redundancy. Each UPS device can be disconnected from the power supply separately. With the integrated manual bypass switch, the complete UPS parallel system can be disconnected.

PRS Rack System

Protection Level: normal

TSE UPS is directly feeding the load. In case of an UPS error will the load still be connected with grid via the internal bypass.

Advantage: Best price.

Single UPS

Protection Level: high

Two UPS systems with shared outputs are feeding the load. In case of an UPS error will the other UPS still supply the load. The maximum allowed load per UPS is 50%.

Advantage: High UPS availability

Redundant UPS

Protection Level: very high

Two independent UPS systems feed two separate power supply units (PSU) of the load. Loads with just one PSU will be supplied by the static transfer switch (STS) which is connected to both UPS systems. The maximum allowed load per UPS is 50%.

Advantage: Very high UPS availability
