Power supply B3-232
The module is meant for providing the no-break electrical power supply of radio electronic equipment. It is a constructively completed product with a built-in cooling system. It can be used autonomously or as a part of the hardware. It has improved electrical compatibility characteristics. The distinctive feature of the module B3-232 is the universality relative to input voltage: the module power supply is performed using a three-phase alternating current network with the voltage (380±57) V and frequency (50±2) Hz or using a one-phase alternating current network with the voltage (220±33) V and frequency (50±2) Hz. The backup power supply by accumulator batteries with the nominal voltage level 24 V (automatic switching in case of miss of network and back after its restoration).
The module provides: - control of the input voltage and deactivating of the module at exceeding or reduction of the input voltage below normal, at phases “stratification”; - control of the output voltage and deactivating at exceeding the voltage norm; - protection from the overload/short circuit, automatic restoration after overload/short circuit; - thermal protection. Main technical characteristics
On the front panel the module has light indication: - of availability of voltage of every phase of the basic supply network 220/380 V; - of availability of reserve accumulators voltage 24V; - of availability of voltage of 27 V at the module output; - of availability of emergency state (doubled by an acoustic signal). |
