ASCO Power Quest - Series 7000 Series

PowerQuest^® VPi is a PC based software package. When combined with the ASCO Communications Interface module (ACC 72A), the ASCO 5120 Telephone Interface Module and the ASCO 5200 Series Power Manager it provides the most economical communication system for monitoring and control of power transfer switches and engine generators.

The RS-485 network allows communications with up to 32 power transfer switches and four engine generators. An analog phone connection and ASCO telephone interface module allow for direct dial up, monitoring and control of remote locations. The ASCO Power Manager not only allows you to view current power and power factor readings, but also has a programmable kW set point to initiate transfer of loads to a standby source for peak shaving operations.

Convenient One-Line Diagram
