It offers a wide input voltage range which allows it to be used in 24V and 48V environments. With a maximum output power of 95W, it can supply up to 4.2A of current, making it suitable for a variety of medium to low power applications. The operation temperature of the unit is from -40°C to +85°C, making it suitable for high temperature environments such as industrial and outdoor applications, and it comes with short circuit, overload, and over temperature protection.

Features

The JCJ1024D12 offers a wide range of features which make in an ideal choice for a variety of applications. It has a wide input voltage range of up to 90V, making it compatible with 24V and 48V systems. Its wide temperature range of -40°C to +85°C makes it suitable for hot climates, and its high efficiency of up to 94% allows it to deliver up to 95W of output power. It also has an integrated EMI filter that helps reduce unwanted noise and interference, and an integrated loop control circuitry which allows for precise and stable regulation of the output voltage. The unit also has a neat feature which allows you to adjust the output voltage from a maximum of +24V to a minimum of +2V, which makes it extremely versatile and convenient. It is also UL 60950-1 listed for safety.

Working Principle

The JCJ1024D12 adopts a non-isolated buck-boost topology to generate the output voltage from the input voltage. The output voltage range is adjustable from 2V to 24V, allowing for a wide range of applications. When the input voltage is within the range of the adjustable output voltage, the DC-DC converter operates in a buck (step down) mode, converting the input voltage into the desired output voltage. When the input voltage is greater than the adjustable output voltage, the converter operates in a boost (step up) mode to generate the desired output voltage. The device is self-contained, so it requires no external components or heatsinks to operate.

The JCJ1024D12 uses an integrated PWM conversion chip to control the switching frequency and output voltage stability. There is an on-chip power management circuit which monitors the output voltage and current to ensure the safety of the unit. It also has an LED indicator to let you know if the unit is operating properly or if there is an issue. The device also has low-ripple output, long hold-up time, short rise and fall time, and is FCC compliant.

In conclusion, the JCJ1024D12 is a reliable and efficient DC DC converter suitable for a wide range of applications. It features a wide input voltage range, adjustable output voltage range, high efficiency, short circuit protection, as well as EMI filters and loop control circuitry, making it an ideal choice for both medium and low power applications. The device is UL 60950-1 listed with a wide temperature range and long hold-up time for reliable operation in hot and hazardous environments. The device also has a low ripple output and FCC compliance, making it a great choice for mission critical applications.
