Open frame power supply TPS-H12SP-12V

AC/DCsingle-outputswitching

Product overview
The TPS-H12SP-12V is an open-frame, single-output power supply from the TPS-H12SP High Voltage Series. Its compact footprint (66 × 30.5 × 20 mm) and light weight (33 g) make it suitable for installations with limited space. The unit accepts a wide input range (100–400 VAC or 127–610 VDC) and uses natural (fanless) cooling for low-noise operation. Rated output power is 10 W with a rated output current of 800 mA (operating range 0–830 mA). The supply is specified for operation from -20°C to +50°C with defined load derating, and employs a 40–60 kHz switching frequency. Output voltage accuracy is ±1% with an adjustable output range of 11.95–12.2 V. Comprehensive protection and safety features ensure reliable long-term operation.
