MODDIY has been specializing in manufacturing premium and custom computer cables and accessories for large corporations, computer enthusiasts, and gamers worldwide for over 13 years. Our cables
The basic concept is that in a dual-supply circuit, "ground" is located halfway between the positive and negative supply voltages. Therefore, all that is
The circuit uses only one active component, a dual MOSFET, which provides the latching logic and acts as a high side power switch/relay. A momentary button
Pin 87 is the connection to a fused power source like your battery or open spot in your fuse box. When the relay is triggered then pin 87 will be connected directly to pin 30 inside the...
This is required and it essential for the circuit to function and not damage the equipment wherever dual supply is required. A simple circuit will solve this

To provide protection against power supply short circuit, it is recommended to connect external diodes (ORing Diodes or Load share modules) when multiple power supplies are connected
Put a Schottky diode between the power supply output and the 12 V lead-acid battery, then adjust the power supply for the desired float charge voltage at the
With Class 0.5 high measurement accuracy, a broad testing range and comprehensive safety protection design, it fully satisfies technical requirements for substation relay inspection,
With a 24-0-24V transformer, LM317/LM337 regulators, and well-considered protection and filtering, this design provides a robust and flexible solution for analog and low-power electronics
Learn how to wire a dual relay system with our detailed wiring diagram. This diagram provides step-by-step instructions for connecting two relays to control
While the power peaks of the laser is a million megawatts, the extremely short duration of the pulses, that last just femtoseconds - a time unit equivalent to one quadrillionth, or one millionth of one
The most important requisite of the protective relay is reliability since they supervise the circuit for a long time before a fault occurs. If a fault then
