Model:
DR-45
Brand:
SMUN

Description:

The DR-45 is a commonly used rail-mounted switch mode power supply, extensively applied in fields such as industrial automation, electrical control cabinets, LED lighting, and security surveillance. Below is a general introduction and overview of its features:

Features:

Rail Mounting: Features a standard DIN rail mounting design for quick installation and maintenance within distribution boxes or control cabinets.
High Efficiency: Operates typically between 76% to 86% efficiency, depending on the output voltage, helping reduce energy consumption and heat generation.
Voltage Regulation: Nominal value is around 10%, ensuring output voltage stability within a certain range despite changes in input voltage.
Low Ripple Noise: As low as 80mVp-p, guaranteeing the purity of power output, especially beneficial for precision circuits.
Reliability: Designed with robust overload and short-circuit protection features, enhancing system stability and safety as an industrial-grade product.

Applications:

Industrial Automation: Powers PLCs, sensors, actuators, and other control components.
LED Lighting: Supplies stable power to small to medium-sized LED lighting fixtures.
Security Surveillance: Powers CCTV cameras, access control systems, and other security equipment.
Communication Equipment: Suitable for small-scale switches, routers, and the like.
Instrumentation: Provides power support for various measuring and testing equipment.

Note	1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line ragulation and load regulation. 4. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.In case the adjacent device is a heat soure, 15mm clearance is recommended 6. Derating may be needed under low input voltage. Please check the derating curve for more details. 7.Please contact with SMUN customer service for more details.
