PH300F48-12

DC-DC converters are essential equipment in most electrical equipment and systems ranging from satellites to mobile phones. They are the key components in power management, allowing energy distribution to and from different circuits within the device. The PH300F48-12 is a high performance DC-DC converter with low temperature requirements and excellent efficiency for end-use applications in industrial, medical, telecommunications, security, and consumer products.

The PH300F48-12 is a 48 V input primary side device with an output of 12 V. It also offers power range of 30 Watts (W). It is a convection cooled, non-isolated, 4-pin SIP type DC-DC converter module with an extended temperature range from 0°C to +65°C (optional). Its wide input range makes it suitable for both traditional and modern Industrial automation systems. It is also known for its high efficiency in power conversion, making it suitable for high power applications.

The PH300F48-12 is also designed with soft-start feature to provide extra protection during start-up. It is designed with protections such as over-voltage, over-current and over-temperature protection as well as an over-voltage lockout (OVLO). It is also provided with an option to enable or disable remote sensing in order to ensure correct voltage at the output.

The working principle of the PH300F48-12 is based on the use of a switching technique. The conversion of the input voltage to the desired output voltage is achieved by using a circuit composed of power semiconductor switches. The switches are periodically switched on and off at a fixed frequency, allowing current to flow through an inductor, and allowing the current to charge or discharge a capacitor. Each capacitor is connected to the input and output side of the converter, providing the energy transfer process. When the switch is closed, the current is drawn from the input side and stored in the inductor. When the switch is open, the energy stored in the inductor is then transferred to the output side, resulting in a voltage conversion.

The PH300F48-12 is a reliable and efficient DC-DC converter with extended temperature range and providing protection features. This makes it an ideal choice for a variety of applications, including industrial automation, medical, consumer electronics, security and telecommunications. Its wide input range, high efficiency and wide operating temperature make it an ideal choice for medium-power applications.
