H12WD4825PGH

Solid State Relays (SSRs) are a type of switch which use a semiconductor device to transition from one state to another, as opposed to a mechanical switch. The H12WD4825PGH is a type of SSR manufactured by IDEC which can be used in various applications. This article will discuss the application field and working principle of the H12WD4825PGH.

The H12WD4825PGH is a 4PDT ("four-pole, double-throw") SSR, which features a high switching capacity of up to 10A/600VAC, as well as the ability to switch on and off at a frequency of up to 1kHz. This makes the H12WD4825PGH ideal for use in applications such as machine controls, lighting systems and power control. Its wide range of ambient temperature (-20°C to +70°C) makes it useful for both indoor and outdoor applications.

The H12WD4825PGH is a contactless component, which means that it does not physically contact the load or power circuit. Instead, it operates using a transmittal communication system. The SSR consists of a light emitting diode (LED), photosensitive transistor (PT), and signal line, which are arranged in a series circuit. When the control signal is activated, the LED emits a light which is then detected by the PT. The PT then turns on the SSR, and the power circuit is able to flow to the load. As the no-contact design of the H12WD4825PGH prevents electrical arcing and spark over, it is very reliable and has a long service life.

The H12WD4825PGH is a versatile and cost-effective SSR, which can be used in a variety of applications. Its high switching capacity and wide range of ambient temperatures make it suitable for a variety of high-power and environmental control applications. Its contactless design also ensures reliable operation and a long service life.
