System Controller; Ups Module (10 Kva / 8 Kw); Static Switch (St/Sw) Module - Gamatronic POWER+ User Manual

1.1

System controller

The POWER + system controller has multiple purposes:
•
To allow the user to manage and control the UPS.
•
To monitor the parameters of all sections of the POWER+ via the control panel.
•
To collect and summarize data from all sections of the UPS.
•
Communicate with external computers for data transfer and operation.
The POWER + can work without the system controller but with reduced functionality.
1.2

UPS module (10 kVA / 8 kW)

The UPS module is the core of the POWER + , which consists of from one to ten identical modules in
parallel depending on capacity requirements.
Each module includes a 3-phase charger with PFC
by a classic DC link. Each module is plug-in and weighs a mere 10 Kg (22 lb.), approximately.
1.3

Static switch (ST/SW) module

The centralized hybrid Static Switch enables an automatic transfer of the load from the output of the
inverters to an alternate source whenever the inverter can no longer supply power to the load. The static
switch can transfer high currents at high speed.

PFC is a feature included that reduces the amount of generated reactive power. Reactive power
operates at right angles to true power and energizes the magnetic field. Reactive power has no real value
for an electronic device, but electric companies charge for both true and reactive power resulting in
unnecessary charges.
In power factor correction, the power factor is the ratio of true power (kWatts) divided by apparent power
(kVA). The power factor value is between 0.0 and 1.00. If the power factor is above 0.8, the device is
using power efficiently. A standard power supply has a power factor of 0.70-0.75, and a power supply with
PFC has a power factor of 0.95-0.99.
