The CHL8318CRT (Current Regulator, Isolated Transformer) is one of the few special purpose voltage regulators that has been designed as a compact module for space-constrained commercial applications. This regulated current transformer is designed to provide an efficient and reliable source of power, while also providing a way to efficiently monitor and regulate load voltage. The CHL8318CRT can provide an accurate current signal to the load over a wide range of operating conditions. Furthermore, this regulator can be used to precisely match the load current to the output of the regulator without any additional circuitry.

The CHL8318CRT is designed to work with a wide variety of external components, such as voltage sources, voltage detectors, and current measurement devices. The device is also designed with an automatic shut-down feature that shuts off the current regulator when a predefined voltage or current limit is reached. This safety feature ensures that the regulated current remains within the specified limits and avoids any over-current or under-current conditions. Furthermore, the device has a high level of accuracy, ensuring that the load voltage remains as close as possible to the programmed value.

The CHL8318CRT consists of two main components. The first is the transformer, which provides isolation between the primary and secondary windings of the transformer, allowing the device to maintain safety and accuracy in the power regulation process. The second is the voltage controller, which consists of a variety of components, such as an analog-to-digital converter, comparators, and logic circuitry.

The CHL8318CRT is capable of supplying current up to 5A, and is designed to operate from input voltages of 6V to 32V. The device is designed to be used in a wide range of applications, such as power supplies for computing, lighting, and industrial control systems. It is also used in medical devices and military systems. The regulator is designed with high thermal performance and low power consumption, ensuring reliable operation. The device also features a wide range of programmable parameters, such as current limiting, load voltage and/or line voltage, current sharing, and adjustable power on and off time.

The working principle of the CHL8318CRT is relatively straightforward. When the input voltage is applied, the transformer transfers the input voltage to the primary winding, which is then further transferred to the secondary side of the transformer via the voltage controller. On the secondary side of the transformer, the voltage is compared to a preset voltage, and the error voltage is then rectified and applied to the output in order to maintain the output voltage within the specified limits. The output current is measured by the current sensing comparators before being applied back to the voltage controller. This allows the regulated output current to be maintained as close as possible to the programmed value.

In summary, the CHL8318CRT is a special purpose voltage regulator designed to provide highly efficient and reliable power regulation. It provides accurate regulation of the load current over a wide range of operating conditions, while also providing safety features to protect against accidental over-current or under-current conditions. The CHL8318CRT is well-suited for a wide range of applications, such as power supplies for computing, lighting, and industrial control systems, as well as medical and military applications. Furthermore, the device provides a number of programmable parameters, such as adjustable power on and off time, current limiting, and load voltage and/or line voltage. The working principle of the device is relatively straightforward, involving the transfer of input voltage to the primary winding of the transformer which is then compared to a preset voltage, with the error voltage being rectified for application back to the output in order to achieve the specified regulation output.
