This product is a 70-120 Watt NTQ123 Series power supply with active power factor correction, EN61000-3-2 compliance, remote sensing on outputs one and two, power fail and remote inhibit, single wire current sharing on outputs one and two, adjustable main outputs, built-in Class B EMI filter, overvoltage protection, overload protection and thermal overload protection.
The NTQ123 Series from Emerson Network Power is a compact power supply offering 70 W convection‑cooled and up to 120 W forced‑air cooling. It supports a wide input voltage range (85‑264 VAC) and includes active power‑factor correction with a typical PF of 0.99.
Key features include overload and short‑circuit protection, remote‑sense on both outputs, adjustable output voltage, and built‑in Class B EMI filtering. The unit meets multiple safety and EMC standards (UL1950, CE, EN61000‑3‑2, etc.) and operates from 0 °C to 50 °C ambient temperature with a hold‑up time of 20 ms at full load.
