230 VAC supply

This module is galvanically separated from the 230 VAC supply. The module is adjusted to direct connection to the electricity network. The module is constructed as a Switch Mode Power Supply, which complies with the requirements for double insulation when mounted in MULTICAL®. When disconnecting the supply, the module will only keep the meter supplied for a few seconds. HC-993-11 and HC-993-12 correspond to HC-993-03 and HC-993-04, respectively, but are delivered with additional connection cables to fit MULTICAL® 803.
