APPLICATION
The TECS20F is an open-frame AC-DC power supply delivering up to 20.4 watts, designed for applications requiring compact size and reliable performance. With universal input from 85 to 264VAC and output options of 5V, 12V, 15V, and 24V, it is well-suited for embedded systems and industrial equipment.
This unit uses SMD technology and achieves typical efficiencies up to 92%, depending on the model. It offers solid electrical performance, including tight regulation, low ripple, and reliable start up, with built-in overcurrent and overvoltage protection for system safety. The TECS20F operates across a broad frequency range (45–440Hz) and maintains a leakage current below 0.1mA.
Compliant with UL62368-1, EN62368-1, and DEN-AN standards, the TECS20F also meets EMC requirements such as CISPR11/32 Class B and EN61000-3-2 Class A. Its wide operating temperature range and vibration and impact resistance make it ideal for use in control systems, communications, and instrumentation where durable, isolated power is needed in a compact open-frame format.
