VE-261-CV Datasheet/PDFDC DC Converters
The VE-261-CV is a DC-DC converter used as a power supply for low voltage applications. It converts AC line power to regulated low voltage DC output for powering electrical devices. It is often used in a variety of applications such as medical equipment, communication systems, and electronic payment systems.
The VE-261-CV field of use includes areas such as security and surveillance, automotive and industrial environments, telecom and data centers, etc. The DC-DC converter meets UL, CSA, CE requirements and can be incorporated into systems certified to IEC60950.
Working Principle
The VE-261-CV DC-DC converter works by first using a power input to convert AC to DC. This DC power is then regulated, or conditioned, using a series of methods.
The first method is an Inrush Current Limiter. This protects the circuit from an initial surge of current that can damage components. This surge is diverted away from the system by a capacitor to protect the circuit.
The second method is an Over-Voltage Protection. This protects components and circuitry from high voltages that can damage components. This is done by a circuit breaker or a fuse.
The third method is an Under-Voltage Protection. This protects components and circuitry from low voltages that can cause various errors and malfunctions. This is done by a voltage regulator.
The fourth method is thermal protection. This protects components and circuitry from high temperatures that can cause short circuits or malfunctions. This is done with temperature-sensing thermistors.
After these methods are used, the DC is ready to be used as the input for the DC-DC converter. The converter itself uses a network of transformers, capacitors, and inductors to convert the DC input into a regulated output voltage that is suitable for electronic components. This output voltage is typically 5 volts, but can be adjusted using a trim potentiometer.
The VE-261-DC is a very useful device for providing low voltage DC power to electronic systems. It helps protect components and circuitry from damages caused by surges and dips in voltage. It also helps regulate the voltage output for the optimal operation of electronic devices.
