EM-TRF-USV

Expansion module for the EASYLAB base component (controller TCU3 or adapter module TAM) that can be directly connected to a 230 V AC supply voltage. The expansion module includes a transformer whose secondary voltage (24 V) is equal to the supply voltage for the controller and the expansion modules connected to it.

Uninterruptible power supply (UPS) by means of a battery pack that maintains defined functions in case of a power failure.

Special characteristics

• Ready for installation, can be easily connected to the main PCB
• Double-stack terminal blocks for 230 V AC supply voltage connection
• Simple electrical connection of expansion module and EASYLAB main PCB using a connection plug
• Simple wiring of switch-operated fume cupboard lighting in combination with the EM-LIGHT expansion module
• Intelligent charge control with trickle charging, deep discharge protection, and reverse voltage protection
• Operating state indicator light
• Controlled response in case of a power failure can be defined (EASYLAB TCU3 with expansion module EM-TRF-USV)
• In case of a power failure: Optical signal on the control panel; configurable alarm signalling

Technical data
