UPS 30 kVA

UPS.30kVA.220/380VAC SYNCHR /ATS/STS/BYPASS/Charge10А

Purpose:

• An off-line Uninterruptible Power Supply (UPS) is designed to back up the supply to electrical loads using energy stored beforehand in batteries. The nominal voltage of the external battery bank is 240 V (20 × 12 V).
• A UPS is required where the supply voltage in the network goes outside permissible limits. A UPS provides fault-free power to the load and protects computers and other industrial and domestic equipment rated 220/380 V AC at 50 Hz, up to 30 kVA for three-phase loads and up to 10 kVA per phase for single-phase loads.
• An off-line UPS with a high-speed thyristor static transfer switch, a built-in charger and an external battery bank provides:
  - short transfer time;
  - minimal conversion losses;
  - low heat dissipation;
  - silent operation;
  - the ability to run for long periods (run time depends on the capacity of the external battery bank) without starting an external diesel generator.
• The UPS has an output for starting an external generator set automatically; an automatic contactor bypass circuit is available as an option.
• When running from batteries, the UPS supplies the load with sinusoidal AC at 50 Hz.
• The UPS monitors the state of the battery and the mains and indicates input and output status.

Distinctive features:

• Pure sine wave output
• Silent, high-efficiency operation
• Apparent output power 30 kVA
• A high-efficiency combined liquid and air cooling system with four cooling levels and five automatic operating modes.
• A backlit LCD control panel showing the UPS output currents and voltages.
• Sensor powered from the DeviceNet network at 11…25 V;
• Audible warning signals indicating the various operating modes, faults and system problems.
• Operating modes and the monitored battery and grid parameters can be programmed from the control panel.
• UPS run/fail signalling relay
• Automatic overload and over-temperature protection
• Programmable deep-discharge battery protection
• Soft start with heavy loads
• Built-in high-speed thyristor static transfer switch.
