Industrial DIN Power Supply
NV-IPW-48-240
EAN: 5904708319882
Industrial DIN-Rail Power Supply (240W, 48V-57V)
Key Features
■ Wide AC power compatibility range (85~264VAC) and stable DC output with a nominal voltage of 48V.
■ High operating efficiency (Efficiency ≥89%) and a power factor exceeding 0.99 @ 115Vac.
■ Integrated system of advanced protection mechanisms, including Over Voltage, Over Current, and Short Circuit Protection with Hiccup mode.
■ Multifunctionality of connection terminals (TB1 and TB2), supporting the connection of both alternating current (AC/L, AC/N) and direct current (DC -V, DC +V).
■ High environmental resistance: operating temperature range from -30°C to 85°C and the ability to withstand voltage impulses across the I/P-O/P level at 1.5kV. The NV-IPW-48-240 model is a compact power supply measuring 45 x 113 x 124 mm and weighing 1.2 kg, designed to deliver a stable 48V direct current (output range: 0-5A) at a maximum continuous power of 240W. The device features a high power factor (> 0.99 @ 115Vac, > 0.93 @ 230Vac) and is capable of handling input voltages in the range of 85~264VAC at frequencies of 47~63Hz, while guaranteeing a very fast startup time (Output Start Time: < 25ms @ nominal input). Installers will appreciate connection flexibility thanks to two sets of terminals.
The TB1 terminals allow for AC/N or DC - and AC/L or DC + connections, while the TB2 terminals provide dedicated DC OUTPUT -V and DC OUTPUT +V outputs.
The system is equipped with automated protection functions, such as Over Voltage Protection (57-70V) and Over Current Protection (6-7.5A), all implemented via Hiccup mode with automatic self-recovery after fault clearance.
Furthermore, the module features Short Circuit Protection that activates upon connecting a sufficiently large copper cable cross-section.
The device features high operational resilience, ensuring load stability at ±1% and a minimal noise level (Wave And Noise: 150mVp-p). The power supply includes advanced protective mechanisms covering Over Power Protection (288-360W) and general Overload Protection, which guarantee an automatic return to normal operation.
Additionally, the module is resistant to vibrations (10-500Hz) and shock impacts (20G), confirming its reliability in harsh operational environments.
