Product Highlights
- Operating voltage ac 90 to 135v 50/60hz. maximum current 15 amp. transfer time less than 30ms (0.03 second). for most smart devices or computers, the switching action of 30ms time will not affect their normal operation.
- Ip68 waterproof high level enclosure, suitable for indoor or outdoor use. flame retardant rating v1. case material: pc (polycarbonate). seal material: silicone rubber. external screw: 304 stainless steel.
- Hcdc hd060 automatic transfer switch, an easy to mount 15amp inline transfer relay provides switching between ac input 2 (utility or shore power) and ac input 1 (inverter or generator) ac source. when ac input 2 is powered, the load power will be switched to ac input 2. when ac input 2 is powered off, the load power will be switched to ac input 1.
- Internal four high power spst relays switch design, effectively avoid the problem of dpdt relay high inductive load arcing. live and neutral wire are switched at the same time. the ground wires of the two inputs and output are connected together internally and will not follow the switch on and off.
- Ac input 1 cable: length 19 inch (0.5 meter), us standard nema 5-15p 3 prong plug. ac input 2 and ac output cables: length 19 inch (0.5 meter), 14awg (2.08 square millimeter) x 3 cores.
