Everyone has definitely experienced a power outage - it does not shine, there is no heat, you do not cook, you cannot write an important document for work… If one of the appliances is damaged after the electrical supply is restored, you have got a problem.
Complaints about appliances due to overvoltage or undervoltage are not accepted by many manufacturers. If you lose your TV, fridge, dishwasher, washing machine or oven without compensation, the damage goes into the tens of thousands. However, situations where the so-called overvoltage (more than standard 230V) or undervoltage (long-term 230V-powered appliance has only 170V from the electrical network) can be prevented in the electrical network for a long time.
- mains voltage monitoring for appliances prone to supply tolerances - undervoltage / overvoltage protection - An adjustable time delay for all types is 0 - 10s (to eliminate short voltage drops or peaks). - Voltage Umin adjusted as % of Umax. - 3-state indication - LEDs indicating normal state and 2 fault states. - the device is powered from the monitored voltage (measures the level of its own power supply) - single-phase design - 1-MODULE, DIN rail mounting.
