SRD-48VDC-SL-C Relay 48V DC Coil, 10A, SPDT, 220VAC, 5 Pin

SRD-48VDC-SL-C Relay 48V DC Coil, 10A, SPDT, 220VAC, 5 Pin

Product Overview

The SRD-48VDC-SL-C from Pro Tronix is a heavy-duty miniature power relay built for systems operating on 48V DC. While 5V and 12V relays are common in small electronics, the 48V version is a critical component for telecommunications equipment, large-scale solar arrays, and electric vehicle charging infrastructures where higher DC voltages are used to reduce current loss.

As an SPDT (Single Pole Double Throw) relay, it offers one common terminal that switches between a Normally Open (NO) and a Normally Closed (NC) contact. Its compact “Sugar Cube” footprint allows it to be integrated into PCBs for power management, signal isolation, and remote switching in high-voltage DC environments.

Technical Specifications

Key Features

• Optimized for 48V Systems: Eliminates the need for voltage dividers or step-down converters in 48V DC native environments.

• Efficient Switching: Manages up to 10A loads with minimal coil heat dissipation due to high-resistance coil engineering.

• Standard Industrial Design: Features the globally recognized SRD-series footprint for easy integration into existing control boards.

• Reliable Isolation: Provides a secure physical and electrical barrier between the 48V control circuit and the 220V AC load.

Common Applications

• Telecom Equipment: Switching power or cooling fans in 48V rack-mounted server and networking systems.

• Solar Battery Banks: Controlling AC inverters or DC loads in 48V off-grid solar energy storage systems.

• Electric Vehicles (EV): Managing auxiliary circuits in 48V light electric vehicles, golf carts, or forklifts.

• Industrial DC Grids: Acting as a control relay in modern factory setups that utilize 48V DC distribution for increased efficiency.
