AC DC Converters

The PBO-3-S9 is an AC-DC (Alternating Current to Direct Current) converter designed for use in industrial control systems. It can be used to power any low-voltage DC system or relay logic circuit that operates on low voltage DC. It has been designed for maximum efficiency, reliability, and safety.

The PBO-3-S9 has a very compact design and is capable of providing up to 18A (Amperes) of continuous output current. It features an auto-restart capability and comes with built-in protections for overload, overvoltage, short-circuiting, thermal shutdown, and reverse polarity. The device is also compliant with UL, cUL, CE, FCC, and RoHS requirements.

The operating principle of the PBO-3-S9 is fairly simple: it takes in an alternating current (AC) input, and converts it into a direct current (DC) output. The DC output can be used to power various circuits and devices such as relay logic and automation systems. The AC input can come from either a 120V or 240V mains supply, and the output can be adjusted from 12V up to 24V.

The AC voltage is first rectified by the PBO-3-S9, which converts it into a DC voltage. This DC voltage is then filtered and regulated to provide a steady output voltage, regardless of the fluctuations in the input AC voltage. The PBO-3-S9 features over-current, over-voltage, short-circuit, and thermal shutdown protections that ensure reliable and safe operation in most industrial control applications.

Overall, the PBO-3-S9 is an excellent choice for applications that require reliable and efficient AC-DC conversion. It is a compact, cost-effective solution for powering low-voltage DC circuits and devices. The device is easy to install and requires minimal maintenance, making it ideal for a wide range of industrial control applications.
