UPS Systems

Our VOLTAGE SWITCHERS protect your most sensitive electronic equipment from the dangers of under or over voltage conditions. The benefit of this unit being that it simply disconnects when the supply falls within acceptable levels. Equipment such as amplifiers, TV’S, HI-FI’S, decoders as well as fridges, freezers and air-conditioners are most susceptible to this form of damage. The voltage switch is available as a 15A unit as well as a 30A unit (Hard Wired)

Servo type 1/1 voltage stabilizers AVR (500VA – 30kVA)

Servo type 3/3 voltage stabilizers AVR (1.5kVA – 300kVA)

Servo type voltage stabilizers use brushes, and armature mechanisms to alter the supply voltage very effective for hardy equipment, but must be serviced regularly due to all the moving parts.

An electronic voltage stabilizer has no moving parts and has a much faster reaction time, used mainly in the telecom’s environment as it needs very little maintenance and offers excellent protection, the electronic voltage stabilizers can be fitted into outdoor enclosures, and can be fitted with isolation transformers.

· Microprocessor DSP Control
