Product Description
The TRACOPOWER TRI 3-4811 DC/DC Converter is an advanced isolated power supply solution engineered for industrial automation, electronics, and instrumentation applications requiring reliable voltage conversion. Designed for 5V DC output and up to 700mA output current, it accepts a wide input voltage range from 36V to 75V DC, supporting flexible system integration where multiple input voltages may be present.
This converter features a reinforced isolation of 5000VAC and ultra-high peak isolation rating of 9000VDC for one second, ensuring robust protection against high voltages, electrical noise, and transient events. The device is capable of delivering up to 3.5W output power, in a compact DIP package with convenient through hole mounting, easing PCB assembly and adaptation into existing circuit boards.
The TRI 3-4811 converter demonstrates reliable performance in harsh environments, supporting continuous operation at temperatures ranging from -40°C to 90°C without derating. With an MTBF value of 5,815,000 hours, it ensures minimal maintenance and downtime for professionally engineered power systems. Efficiency up to 82% reduces power loss, and low no-load power consumption (96 - 192mW) enhances energy savings.
Protection mechanisms against overload, overvoltage, and short circuit are integrated, safeguarding sensitive electronic circuits. Additional design features such as common mode transient immunity (dv/dt) of 15kV/μs support signal integrity in demanding industrial settings, while a 2:1 input ratio allows the TRI 3-4811 to handle variable input conditions reliably.
The converter’s seven-pin DIP format, compact form factor (31.8mm x 20.3mm x 12mm), and universal compatibility make it ideal for applications including industrial controls, remote measurement and telemetry, laboratory instrumentation, and any scenario where precise isolated DC power is vital.
Industries benefiting from this solution include manufacturing automation, industrial equipment, telecom, instrumentation, railway, energy management, and laboratory setups. The TRACOPOWER legacy ensures quality and reliability, with a three-year product warranty supporting critical infrastructure.
