Q: What is the difference between an AMF Panel and an ATS Panel?

An ATS (Automatic Transfer Switch) Panel only handles the switching of electrical loads between two live power sources (Mains and Generator). An AMF (Auto Mains Failure) Panel includes full ATS switching capability PLUS the engine intelligence to automatically start, monitor, protect, and stop the diesel generator set.

Q: Can an AMF Panel work with PLC and SCADA automation?

Yes. Panel Electro AMF Panels come equipped with RS485 Modbus RTU, Ethernet RJ45, and potential-free dry contacts. They easily interface with plant PLCs, BMS (Building Management Systems), and central SCADA networks for remote monitoring, logging, and automatic control.

Q: How fast does an AMF Panel start the generator and transfer load?

The initial mains failure detection occurs in under 100 milliseconds. The total load transfer time (including generator engine cranking and voltage stabilization) is typically between 3 to 8 seconds depending on generator size and crank settings.

Q: Does the AMF Panel protect the generator engine?

Yes. The AMF controller provides comprehensive engine protection including Low Oil Pressure (LOP), High Water Temperature (HWT), Under/Over Speed, Fail-to-Crank, Over-Crank, Charging Alternator Fail, and Low Fuel Level lockout alarms.

Q: What components are used in Panel Electro AMF Panels?

We use Tier-1 global switchgear brands including Deep Sea Electronics (DSE), ComAp, or SmartGen for AMF controllers; ABB, Schneider Electric, Siemens, or L&T for motorized changeovers, MCCBs, ACBs, and contactors; and 99.9% ETP copper busbars.

Q: What happens when mains power is restored?

The AMF panel senses stable mains voltage for a pre-programmed delay (e.g., 30 seconds to ensure grid stability). It then transfers the load back to utility mains without interruption, keeps the generator running idle for a cool-down period, and automatically stops the engine.

Q: Is manual override possible in an AMF Panel?

Yes. Every Panel Electro AMF Panel features a 4-position selector switch (AUTO / MANUAL / TEST / OFF) and manual pushbuttons on the front door, allowing operators to manually start the generator or perform maintenance testing at any time.

Q: How does the built-in automatic battery charger work?

Our AMF panels include a constant-voltage, current-limiting automatic float/boost battery charger (12V / 24V DC) fed from utility mains. This ensures the generator start battery remains 100% charged and ready for immediate cranking at all times.

Question 1

What is an AMF Panel (Auto Mains Failure Panel)?

Accepted Answer

An AMF Panel (Auto Mains Failure Panel) is an electrical control board that automatically monitors utility grid power. When mains power fails or drops below preset voltage/frequency limits, the AMF panel signals the diesel generator (DG set) to crank, start up, and automatically transfer the facility's electrical load to the generator. When grid utility power restores, the panel switches the load back to utility power and runs the DG set on a cool-down cycle before shutting it off.

Question 2

How does an AMF Panel work during a power outage?

Accepted Answer

1) Voltage sensing relays detect utility mains failure or phase drop (<100ms).
2) The microprocessor AMF controller triggers the generator starter motor solenoid.
3) Once generator voltage and frequency reach rated levels (typically 3-5 seconds), the motorized transfer switch or interlocked contactor/ACB closes to feed the load.
4) When utility mains power is restored and stabilized, the panel switches load back to mains and runs the generator on a 2-minute cool-down timer before stopping the engine.

Question 3

What is the difference between an AMF Panel and an ATS Panel?

Accepted Answer

An ATS (Automatic Transfer Switch) Panel only handles the switching of electrical loads between two live power sources (Mains and Generator). An AMF (Auto Mains Failure) Panel includes full ATS switching capability PLUS the engine intelligence to automatically start, monitor, protect, and stop the diesel generator set.

Question 10

How does the built-in automatic battery charger work?

Accepted Answer

Our AMF panels include a constant-voltage, current-limiting automatic float/boost battery charger (12V / 24V DC) fed from utility mains. This ensures the generator start battery remains 100% charged and ready for immediate cranking at all times.

Question 11

Can the AMF Panel send SMS alerts or connect to Cloud IoT?

Accepted Answer

Yes. Optional GSM/GPRS or Ethernet telemetry modules allow the AMF controller to send real-time SMS alerts, email notifications, and live status data (mains status, DG run hours, fuel level, battery voltage) to mobile phones or Cloud IoT portals.

Question 12

What maintenance is required for an AMF Panel?

Accepted Answer

Periodic maintenance includes inspecting cable terminations, checking battery charger voltage, cleaning ventilation air filters, and running the automatic no-load scheduled test run once a month to verify engine crank readiness.

Question 13

Can an AMF Panel handle multiple generators (synchronization)?

Accepted Answer

For multi-generator installations, we manufacture DG Synchronizing & Load Sharing Panels that integrate AMF logic with automatic generator auto-synchronizing, auto-load sharing, and load shedding controllers.

Question 14

What safety interlocks are provided in the AMF Panel?

Accepted Answer

We incorporate both electrical and mechanical interlocks between the Mains supply breaker/contactor and Generator breaker/contactor to mathematically prevent back-feeding generator power into a dead utility grid.

Question 15

What degree of protection (IP rating) is offered?

Accepted Answer

Standard indoor panels are IP42 or IP54. Outdoor weatherproof installations are supplied in IP55 or IP65 double-door enclosures with rain hoods, dust filters, and thermostat-controlled cooling fans.
