The Eterna Dual Voltage Shaver Supply Unit (DVSS) is an essential installation for modern bathrooms, designed for homeowners and electricians looking for a safe, code-compliant way to power electric shavers. It provides the necessary electrical isolation for appliances used near water, though users should note it is intended for intermittent operation and may not be compatible with the charging requirements of certain electric toothbrush brands.

The unit is specifically designed for electric shavers. It may not provide enough power or the correct charging protocol for other high-drain appliances.
You must use a backbox with a minimum depth of 47mm to house the transformer safely.
It is IP41 rated, meaning it is protected against dripping water, but it is not waterproof and should never be submerged or directly sprayed with water.
The thermal cut-out acts as a safety mechanism that disconnects the power if the unit exceeds safe operating temperatures, preventing damage or fire hazards.
Yes, it provides both 115V and 230V isolated outputs to accommodate various shaver types.
It is designed for intermittent use for shavers and is not intended to provide continuous power for long periods.
Verify that the shaver is firmly inserted and test with a known-working appliance; if the issue persists, the thermal cut-out may have triggered due to an overload.
Unplug the device immediately and allow the unit to cool; ensure the connected appliance does not exceed the unit's rated intermittent capacity.
The unit is designed for shavers; check if your toothbrush charger requires a higher constant power supply than this unit is rated to provide.
Installation should be performed by a qualified professional to ensure compliance with local wiring regulations. The unit requires a recessed backbox with a minimum depth of 47mm to accommodate the internal transformer. Dimensions are 145mm in height and 85mm in width, with a rear projection of 36mm. To maintain the unit, keep the front faceplate clean by wiping it with a dry or slightly damp non-abrasive cloth. Avoid spraying water directly onto the unit or using chemical cleaners. Periodically check the unit for any signs of surface damage or discoloration, which could indicate internal component stress.
