TP20DD Series

Product catalog summary

Description: The TP20DD Series converters offer a rated output power of 20W with dimensions of 50.8mm x 40.6mm x 11.2mm. They support wide input voltage ranges of 2:1 and 4:1, covering 9V-18V, 18V-36V, 36V-72V, 9V-36V, and 18V-72V DC. The converters are highly accurate with a precision of ±1% and are suitable for telecommunications, railway transportation, and instrumentation applications.

Features: Key features include 20W output power, input under-voltage protection, a metal shielding package, an operating temperature range of -40°C to 85°C, fixed switching frequency, long-term short-circuit protection, and RoHS compliance. The converters also provide 1.5KVDC isolation.

Selection Guide: The document provides a detailed selection guide with part numbers, input voltage ranges, output voltages, currents, and typical efficiency percentages for various models.

General Characteristics: The converters have an isolation voltage of up to 1500 VDC, insulation resistance of 100M Ohm, and a seismic rating of 5G. The MTBF is rated at 500,000 hours according to MIL-HDBK-217F2 standards. Cooling is achieved through free air convection, and the case is made of metal.

Output Characteristics: Voltage accuracy is maintained at ±1%, with line and load regulation at ±0.2% and ±0.5% respectively. The converters feature over-current protection and a transient recovery time of 400 microseconds.

Input Characteristics: Startup voltages vary by module, with input under-voltage protection thresholds specified. The startup time is 20ms, and remote control options are available.

Environmental Characteristics: The converters operate in humidity levels of 5% to 95% and temperatures from -40°C to 85°C. Storage temperatures range from -55°C to 125°C, with a maximum case temperature of 105°C.

Mechanical Dimensions and Pin Connections: Detailed mechanical dimensions and pin connections for single and dual output configurations are provided.

Using Attentions: The document warns against irreversible damage due to input reverse polarity, long-term overload, and exceeding maximum input voltage ranges. Recommendations for input and output capacitance to improve electromagnetic compatibility and stability are also included.
