- battery
- control system and signalling
- DC protection circuitry
DC backup power supplies - are used mainly for supplying of control voltages in distribution plants, supplying of various control systems as well as emergency lightening.
Modular backup power-supplies - a rectifier consists of several modules in parallel to increase reliability mainly in unmanned plants.
Thyristor backup power supplies - are used for higher power outputs and longer backup times.
Monoblocks - compact backup power supplies in one cabinet including batteries and tailored DC output protection.
DC switchboards - solve customer requests for connection of rectifiers, batteries, protections, operational as well as service buses, and possibility of diagnostic of different operating conditions.
