The differential pressure controller is designed for continuous - both automatic and manual - control of the supercharger operation in order to maintain the required excess air pressure in the pneumatic module frame. DPC also serves as a distribution board for power supply network of pneumo module consumers ~220V 50Hz. DPC should be operated in the pneumatic frame structures’ rooms with relative air humidity not exceeding 98% at +25°С. DPC is supplied in the same enclosure with a circuit breaker of the pneumo module lighting network and GFCI (ground fault circuit interrupter) with built-in overcurrent protection (“differential automatic device”) of consumer sockets. A pressure switch is connected to the DPC housing (a complete DPC article); A shipping case is supplied as a complete set and serves for transportation and storage of the DPC, pressure switch and connecting cables.
