MS22 22103

Inrush current limiters (ICLs) are devices used to protect equipment from inrush current surge in power supplies. In a power supply system, current pulses can cause a large amount of current to flow into a system, potentially damaging the system and its components. ICLs can address this issue by reducing the inrush current surge, allowing for a more efficient and safe operation of appliances and circuits.

The MS22-22103 is an ICL designed to limit the maximum inrush current pulses generated during power-up, which can reach up to 10A in 120VAC systems. It is used in a range of applications including solar power supplies, motor controllers and industrial equipment. It works by limiting the current flow through an internal resistor element.

The MS22-22103 has a maximum operating temperature of 70°C and works on a wide range of input voltages (1-265VAC). It also features an internal thermistor which prevents the inrush current in the event of a power surge or large transient. The device has a peak current rating of 12A, with a pulse duration of up to 2ms under normal operating conditions. It has a coil resistance of 85Ω and can handle up to 1Ω of inductive load.

The internal resistor element in the MS22-22103 is designed to dissipate the energy generated during the inrush current limiting process. This ensures that the energy is safely dissipated, avoiding damage to the system components. The resistor is connected to a capacitor, which helps to reduce the transient voltage during power-up. This helps reduce the potential for sparking at the connection points.

The MS22-22103 is a cost-effective solution for protecting against inrush current surges in power supplies. It is designed to reduce the peak current load and ensure that the system operates safely and efficiently. The internal resistor element helps dissipate the generated energy, while the capacitor helps reduce transient voltage. With its compact size and wide input voltage range, the MS22-22103 is well suited for a variety of applications, from solar power supplies to motor controllers.
