An Electronic Protection Switch (EPS15) is a semi-conductor device that is designed to provide electrical protection and circuit current control against high voltage, surge current and transient voltage. It is primarily used in high current circuit and power supply applications. The EPS15 series of turn-on switches is based on Thyristor technology which provides protection against high voltage, surge current or transient voltage in industrial power systems.

EPS15 turn-on switches operate by triggering the activation of a thyristor. This thyristor, when energized, forms a conductive path that allows current to flow through the switch and to the load. This function protects against high voltage, surge current and transient voltage. The switch is typically designed to turn off at a certain voltage or current level which provides additional protection against voltage and current spikes.

The EPS15 switch can be used to control circuits that have current levels up to 1100 amps and is rated for applications up to three thousand volts. It is designed to support industrial applications such as motors, HVAC equipment, lighting, industrial equipment and machinery. It offers a variety of protection and control features including over current protection, power on/off functionality, adjustable current levels and overload protection. The EPS15 is compliant with UL standards and is UL listed.

The working principle of the EPS15 switch is based on thyristor technology. A thyristor is a semi-conductor that has four leads. It is composed of two P-type and two N-type semi-conductor layers, and has positive and negative terminals. The P-type layer is connected to the positive terminal and the N-type layer is connected to the negative terminal. The two layers are connected in series, forming a bi-directional switch. When the current through the circuit is high, the thyristor is triggered, turning the current flow on or off and providing protection against high voltage, surge current or transient voltage.

The EPS15 switch can be triggered by a variety of methods including direct control from a control circuit, or from an external thermal switch or pressure switch. The switch can also be triggered manually using a push button. The timing of the switch can be set to delay the response and turn-on time to prevent unintentional triggering or damage. Additionally, the EPS15 can be set to allow a normal on-off operation, or to provide a pulse-width modulation (PWM) operation for current control applications. The adjustable current can range up to a maximum of 20 amperes in PWM mode.

The EPS15 turn-on switch is a reliable and durable device designed to provide current control and protection for industrial applications. It provides protection against high voltage, surge current or transient voltage, and adjustable current levels. It can be triggered manually or by external control devices, and the adjustable timing can be used to prevent unintentional triggering or damage. It is compliant with UL standards and is UL listed.
