The MarPower SPC-II HYBRID is the ultimate alternative for isolation transformers due to its small size and extremely low weight and added functionality.
The MarPower SPC-II HYBRID has all the benefi ts and features of the standard SPC-II, however has at higher input voltages almost double the output power due to the use of a hybrid cooling system, while the size and weight are only increased marginally. Hybrid cooling is an innovative way of cooling, which uses both liquid cooling as well as air cooling. In case the liquid cooling fails, the unit can run with reduced power as a standard SPC-II.
