The US1KHR3G is a member of the diode rectifier family. It is a single-phase rectifier designed to protect motor controllers from high voltage and current under extreme conditions. The device offers both high voltage protection and current limiting protection, with a breakdown voltage rating of up to 3,000 volts peak, and a current limit of up to 1,000 amperes (A).

The US1KHR3G is designed to be mounted on the same chassis as the motor controllers, and is designed to interface directly with them via built-in connectors. It is capable of detecting high voltage conditions and rapidly reducing the voltage to a safe level within the operating range of the motor controllers. The device also has a current limiting feature, which is capable of limiting the current to within a safe level, in the event of an overload or short circuit.

The US1KHR3G is typically used in industrial motor control applications, such as electric motors, pumps, and linear actuators. It is ideal for protecting sensitive electronic components from transient voltage spikes or inrush currents caused by rapid startup or heavy loading of the motor controllers. The device is also suitable for high-voltage power supplies, such as solar and wind power systems, for use in overvoltage protection.

The working principle of the US1KHR3G is based on the principle of reverse-blocking diode. A diode is a semiconductor device that blocks the flow of electric current from one direction and allows it to flow in the opposite direction. When a diode is reverse-biased, it acts as a switch, blocking current in one direction and allowing current to flow in the other direction. The US1KHR3G is designed to operate in reverse-blocking mode when high voltage or current conditions are detected, transferring the energy to a safe level.

The US1KHR3G has a triggering voltage and current threshold that is set to the desired limit. Once the voltage or current exceeds the threshold, the diode quickly switches to the reverse-blocking mode, reducing the voltage or current to a safe level. The device can be reset manually, or by using a failsafe mechanism that automatically resets the device once the voltage or current falls below the threshold. The reset time for the device is typically less than 1 millisecond.

The US1KHR3G is a reliable and durable device that offers superior protection for motor controllers. It is designed to withstand a wide range of temperatures, and it is capable of handling extreme high voltages and currents. Its compact size makes it easy to install and integrate with existing motor controllers. The device is UL and CSA certified, ensuring its reliability and safety in a wide range of applications.
