Power Relays, Over 2 Amps

The VF4A-11F11 is a power relay designed for applications that require high power switching. The device is a multipurpose device that can be used for both AC and DC power switching and comes with several features that make it suitable for a variety of applications. It is encased in a Polyamide 6.6/UL 94V-0 case and is rated for operations up to 50A at 250V AC or Constant Current/Voltage (CC/CV).

Application field

The VF4A-11F11 is a multi-purpose power relay that can be used for many different applications. It is suitable for power control of low voltage DC and AC circuits and is also suitable for overload, thermal, and short circuit protection of DC power systems. It can also be used as a switching regulator for precision control of DC power output.

The device is also suitable for switching operations such as switches, relay logic, timer circuits, and other applications such as oscilloscope triggering and motor control. It is also suitable for use in machines like vending machines, conveyors, sensors, and safety systems. The VF4A-11F11 can also be used for circuits designed for motor control, circuit switching, and reversible control.

Working Principle

The VF4A-11F11 is a power relay with two coils; one for controlling the operation of the relay and the other for controlling the output voltage. The first coil is connected to the main AC power source and the second coil is connected to the output voltage. The first coil will produce a magnetic field which acts on the second coil which in turn activates the closed circuit driving the output voltage.When the main AC power is applied to the first coil, the magnetic field produced will actuate an electromechanical operating lever which switches the load current from the second coil to the load, thereby activating the output voltage. The other coil acts as a resistive load and maintains the output voltage. The relay can be tuned by adjusting the voltage and current to the second coil, thereby controlling the output voltage.

The VF4A-11F11 is designed to be reliable and durable and, with proper installation and maintenance, can be used for many different applications. It is designed to meet both domestic and international safety standards and comes with a variety of accessories such as mounting bases and terminals that make mounting and connecting the relay easy and reliable. This power relay is suitable for use in many different environments and applications and is highly reliable and easy to operate.
