Seven Product Ranges

Everything between the mains and the load.

Pick the range you need. Every item is quoted against your load, so you pay for the rating you actually require.

How The Range Fits Together

Protect the supply. Back it up. Keep people safe.

Three jobs, seven products. Choose one range or specify the whole set from a single source.

Protect

Voltage stabilizers

Servo and step stabilizers keep motors, machines and electronics running on a steady voltage.

  • Servo voltage stabilizers, 1 phase and 3 phase
  • Air cooled and oil cooled models
  • Step voltage stabilizers

Back up

UPS, inverters & batteries

Power that carries on when the mains does not, with the chargers and batteries behind it.

  • Online UPS, 1 phase and 3 phase
  • Inverters, 1 phase and 3 phase
  • Battery chargers
  • Industrial and automotive batteries

In-House Manufacturing

AAYEKA emergency lights and stabilizers.

AAYEKA builds its own emergency lights, exit signage and servo stabilizers. Because we make them, we can meet a specification rather than offer the nearest catalogue item.

  • Domestic and industrial emergency lights, including twin-head units
  • EXIT and emergency egress signage marked to IS 10322 (Part 5/Sec 8): 2013
  • Flameproof variants for hazardous-area installations
  • Servo stabilizers, single and three phase, air or oil cooled
