The Be28 is 3-phase Automatic Transfer Switch controller. All parameters, alarms and operating functions are indicated by means of a high-luminosity display. The ATS controller Be28 interfaces with digital inputs and analog inputs via Bluetooth based modules. The controller provides accurate measurements for Vac, Aac, Vdc, Hz and Battery Vdc on display. You can check the LOG EVENTS on site and have an overview of the all settings. The Be28 features MODBUS via RS485 and complies with NFPA-110 / NFPA-99. By using our TCP-IP server you can monitor and control the Be28 via INTERNET. You can interface this automatic transfer switch controller with a GSM SMS server in a way to get access via SMS.
The automatic transfer switch controller continuously monitors the status of the utility power (or MAINS if you will). You can set low/high limits for Mains Voltage and Frequency. When the voltage and the frequency are within the limits, the automatic transfer switch controller transfers the load to the utility power. If the voltage drops below the lower limit (or rises above the high limit), the automatic transfer switch controller will disable the Mains circuit. This prevent, after a programmable delay, a severe damage to your load. If the failure persists for a long time the automatic transfer switch controller will take care to start the generator . Once again the automatic transfer switch controller does its business to check the quality of the generator voltage and frequency. To get best performances from Be28 automatic transfer switch controller, we recommend that you supply the panel by using the battery of the engine. The automatic transfer switch controller will guarantee remote control monitoring when there is no utility power. It will properly manage the automatic transfer switch when utility power or generator voltage are not stable. You can use a 12V or 24V battery. The automatic transfer switch controller features adjustable inputs & adjustable outputs providing extraordinary system flexibility.
