ALT-100-3-SW

ALT-100-3-SW Power Relays, Over 2 Amps

The ALT-100-3-SW, an over 2 amps power relay, is a three-pole relay designed for use in digital electronics and power control applications.

The main feature of this power relay is that it can be used as an independent switch for providing power control to a variety of applications. It can be used as a main switch for switching power or as an auxiliary switch for controlling an auxiliary function. With the addition of a single base, it can also be switched at multiple locations, for applications requiring power switching or monitoring.

The ALT-100-3-SW is constructed from a solid state relay with a normally open (NO) contact. Internally, a power relay consists of two electrical coils, which are wired to the NO contact. With power applied, one of the coils is energized and turns on the internal switch, which then allows power to flow through the NO contact. The other coil is also energized, providing a continuous contact for power control.

The ALT-100-3-SW offers the following applications areas:

• Switching of digital electronics components
• Control of power applications
• Data switching
• Power supply control
• Controlling auxiliary functions

The working principle behind this power relay is based on the concept of electromagnetism. When power is applied to the relay, the two coils create a magnetic field that induces a voltage in the NO contact. This voltage is used to open the contact and allow power to flow through.

When the power supplied to the relay is removed, the two coils de-energize and the contact closes, thereby restricting the power flow. The ALT-100-3-SW offers a wide range of voltage and current ratings, making it suitable for a variety of different power control applications.

The ALT-100-3-SW can also be used to monitor and switch digital logic circuits and to protect vulnerable components from damage caused by over-current or reverse polarity conditions. The power relay also provides protection against short-circuiting and harmful power spikes.

In summary, the ALT-100-3-SW is an efficient three-pole power relay suitable for over 2 amps power control applications. It is constructed from a solid state relay with a normally open contact, and offers a wide range of voltage and current ratings for versatile power switching options.
