Product Description

VAU01.1U-24-24-240-NN is an industrial uninterruptible power supply (UPS). It is manufactured by Bosch Rexroth. The UPS is part of the VAU product line. The UPS can provide backup power for up to 3 minutes. Its input voltage is 24 Volts DC and the maximum input current is 12 Amps. The output voltage is 24 Volts DC and the maximum output current is 10 Amps. The peak power output of the VAU01.1U-24-24-240-NN UPS is 240 Watts. The UPS requires less than 1 milliseconds to switch on its output after input power loss. The switch-on threshold is 15.5 Volts and the switch-off threshold is 20.2 Volts. Bosch has designed the UPS with an IP20 rated enclosure. Therefore, it can be used indoors. Outdoor use is only possible when the UPS is installed inside a cabinet. Bosch has designed the device for top-hat rail mounting. Weight of the UPS is 3.5 kilograms and its dimensions are 145 x 128 x 123 millimeters. During operation the ambient temperature should be between 5 and 45 degrees Celsius. During storage and transport, the ambient temperature should be between -20 and 60 degrees Celsius. For both operation and storage, the UPS can sustain temporal temperature changes of up to 3 degrees Celsius per minute. The approximate service life of the rechargeable battery is 10 years at +25 degrees Celsius. The battery service life reduces by half with each successive 10 degree Celsius temperature rise. Operators can check the rechargeable battery via a monitoring circuit controlled by the connected computer. If the voltage falls below a threshold, the red color 釘att. low" LED at the front panel turns on. In this state, the UPS cannot provide backup power. If the LED is still on 5 hours after switching on the UPS, operators must immediately initiate a replacement of the rechargeable battery.
