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.
