Ekhwesi: Single Phase Din Rail Pre-paid Meter

Ekhwesi's new wBEC44 integrated wireless meter range provides the building block for a revolutionary new smart solution. The compact DIN rail meter is packed with features to enhance customer satisfaction, whilst providing the valuable data needed by utilities worldwide.

Added to this is the ability for the meter to operate as a prepayment or post-payment meter, depending on the utility's requirements. The greatest benefit and cost saving is that through the use of integrated radio frequency (RF), the meters are not subject to line interference and don't require the costly addition of filters, Making this a simple, quick and cost effective solution for today and tomorrow.

Main Features

• Operates as prepayment or post-payment meter
• Configurable credit management options
• Thermal shutdown protection
• Reverse energy management
• Delayed reconnection
