Uninterruptible power supply
Guaranteed power for special communications gear, computing complexes and telemetry nodes requires fault-tolerant hardware. Defence enterprises, security agencies and systems integrators can buy an uninterruptible power supply in Minsk directly from the developer — Engineering TiM — with a guarantee of full compliance with industry specifications.
The UPB 400 module provides continuous DC load power in the 20.9–29.4 V range at a rated 400 W from 230 V mains or from the battery pack included with the product. Built-in short-circuit and reverse-polarity protection prevents equipment failure on external-line faults and protects sensitive electronics.
How to choose an uninterruptible power supply for a specific task
When designing power nodes for special equipment, DC output voltage, current margin and mass/size for chassis or rack integration are critical. The design office adapts UPS topology to non-standard bay sizes and shock/vibration requirements.
Technical selection criteria:
Autonomy: the BA 27400-25.2-001 battery from the delivery set provides at least 60 minutes of continuous operation at a rated 400 W load.
Bump-free switching: DC bus voltage stays stable without dips or delays when primary mains is lost.
Hardware monitoring: built-in self-diagnostics with signal lines for mains, output, battery state and charge faults for integration into a central control loop.
Compact layout: 160×120×170 mm and 2 kg mass ease integration into mobile complexes.
Typical applications and equipment compatibility
UPB 400 is designed for special-purpose equipment, fixed and mobile automated workstations (AWS), control gear and transmit/receive paths. A remote-start option enables powering equipment from the operator bay without direct access to the unit’s power panel. The −20 to +40 °C range supports open ranges and unheated hardware containers.
When building a shared power contour for monitoring and radio-intelligence posts, the power scheme supports joint operation with adjacent systems.
