Interlocking Solutions


Designed for power supply of Relay interlocking on large-scale stations and ABTC/ABTC-EM

Autonomic power supply of Interlocking systems minimum 2 hours

Compatible with any earth systems using IFU

Power supply of DC track switches



CUPSP 200R + ABTC is intended for high performance uninterruptable power supply of Relay interlocking with track switches up to 200 together with ABTC and ABTC-EM. Plant can be used inside the EI buildings.



The plant has the combined construction with common input BABT, distribution board and three transformer boards: TB1 and TB2 – for power supply loads of MI and TB-3 – for power supply loads of ABTC.

Isolated power poles from 7 to 25 V high capacity are intended for light indication on the different displays where flashing poles are implemented on contactless solid contactors and relays basis.

The UPS is used for providing uninterruptible power supply of Interlocking systems amounting to CPSP. The system consists of three industrial parallel supply units GE DE. The switching time from storage batteries during disappearing external network is zero. All critical elements and functions are reserved and the single refusal point is absent. The system is based on the power backup n+1 principle in which failure of one USU doesn’t lead to overload other. This solution also allows the maintenance work of any USU without power supply interruption. Unit has Russian interface and possibility of remote diagnostic by systems STDM.

CPSP 200R could power supply of DC and AC switch motors.
