Key Features & Benefits
-
High Power & Stable Output:Â 1500W total power with a single, clean 27V DC / 56A output. Perfect for driving high-current devices without performance fluctuations.
-
Universal AC Input (90-264VAC):Â Automatically adjusts to nearly any mains power voltage around the world, simplifying installation and enhancing versatility.
-
High Efficiency (up to 91%):Â Reduces power loss and heat generation, leading to lower operating costs and improved long-term reliability.
-
Active Power Factor Correction (PFC >0.95):Â Meets international harmonic current standards (EN61000-3-2), minimizes energy waste, and is ideal for use in industrial settings.
-
Comprehensive Protection: Built-in safeguards including Overload (OLP), Over Voltage (OVP), Over Temperature (OTP), and Short Circuit (SCP) protect both the power supply and your valuable connected equipment.
-
Forced Air Cooling with Smart Fan:Â A temperature-controlled fan ensures optimal thermal management under high load, maintaining performance and extending component life.
-
DIN Rail Mountable:Â Designed for easy and secure installation on standard DIN rails (TS-35/7.5 or 15), making it a perfect fit for industrial control panels and automation systems.
-
Cooling Fan On/Off Control:Â TheÂ
ON/OFFÂ terminal allows for external control of the cooling fan, enabling silent operation during low-load conditions. -
Power Good Signal:Â TheÂ
P.G. signal provides a remote status indicator, allowing systems to monitor the health of the power supply.
