1. Circuit for complementing an ac mains voltage, particularly for resistive loads

2. The machine logic unit (31) has a network part (31a) for converting electrical mains voltage into low voltage.

3. This unit auto-senses the mains voltage, and adjusts accordingly, so is most likely to benefit international travellers.

4. Unlike other chick heating plates on the market the EcoGlow Chick Brooders run at a low voltage - a much safer option than mains voltage chicken heating plates or suspended heat lamps.
