Solid State Relays – 25A, 50A & 75A | 240V AC Input, 3–32V DC Control

Reliable Panel-Mount Power Switching for Industrial and Commercial Applications

Product Description:
These Solid State Relays (SSRs) provide high-performance, reliable switching for AC loads in industrial, commercial, and automation applications. Available in 25A, 50A, and 75A ratings, they offer flexible solutions for controlling resistive and inductive loads with precision and minimal maintenance.

Designed for panel mounting, these SSRs simplify installation in control panels, distribution boards, or automation cabinets. With a 240V AC load input and 3–32V DC control input, they are compatible with a wide range of control systems, including PLCs, microcontrollers, and industrial switches.

Key Features:

• Load Current Ratings: 25A, 50A, 75A

• Input Voltage (AC): 240V AC

• Control Voltage (DC): 3–32V DC

• Switching Type: Zero-cross or random turn-on (depending on model)

• Mounting: Panel-mount design for secure installation

• Protection: Short-circuit and thermal overload protection (depending on installation)

• Isolation: Full electrical isolation between control and load circuits

• Operation: Maintenance-free solid-state switching, silent operation

Benefits:
✔ High current handling for a wide range of AC loads
✔ Reliable, maintenance-free operation with long service life
✔ Compact panel-mount design for easy integration
✔ Rapid switching with minimal electrical noise
✔ Safe control with full electrical isolation between control and load

Typical Applications:

• Industrial heating and HVAC systems

• Motor and pump control

• Automation and process control systems

• Lighting, resistive, and inductive load switching

• PLC and microcontroller interfacing
