DC voltage regulator RN 12V/5A RN500

Voltage stabilization in CCTV systems and beyond

The DC RN 12V/5A voltage regulator is a reliable device that lowers and stabilizes voltage from 12V-14V DC to 12V DC. Its design allows for efficient use of energy from the battery, especially in emergency power systems. It is an ideal solution for installers and users who need precise and stable power for sensitive devices.

This regulator is specifically dedicated to CCTV (cameras, IR illuminators) and access control (KD) systems. It will work anywhere where a stabilized voltage of 10V-12V DC is required, and direct connection to a 13.8V DC power supply could damage connected devices.

• Wide input voltage range: Accepts a power supply voltage in the range of 9-14V DC (-/+5%), ensuring compatibility with various power sources.
• Voltage stabilization: Provides precise stabilization of the output voltage at 12V DC (with adjustment in the range of 11V - Uin), protecting connected devices from overvoltage and undervoltage.
• High efficiency: When the input voltage drops below the set threshold, the regulator opens the transistor and conducts without loss (voltage drop below 1%), maximizing the use of battery energy.
• Protections: Equipped with short-circuit protection (SCP) and overload protection (OLP), which protects both the regulator and connected devices. If the permissible power is exceeded, a resettable PTC fuse limits the current and requires manual restart after disconnecting the load.
• Optical signaling: An LED indicates the DC power status (red) and the correct operation of the DC output (green), making diagnosis and monitoring of the device easier.
• Compact dimensions: Dimensions of 76 x 70 x 45 mm allow for easy integration into various installations.

Design and application

The RN500 regulator has an “open-frame” design (without a housing), which facilitates mounting using mounting pins or double-sided tape. The outputs are equipped with screw terminals accepting wires with a cross-section from 0.41 to 1.63 mm² (AWG 26-14). It is important to ensure adequate airflow around the module for effective convective cooling.

Thanks to its reliability and functionality, the RN500 regulator finds application not only in CCTV and access control systems, but also in other applications requiring stable 12V DC power, such as:

• Alarm systems
• Home automation
• Electronic devices sensitive to voltage changes
• Audio-video equipment power supply

This regulator complies with CE and RoHS standards, guaranteeing its safety and compliance with environmental regulations. The manufacturer's warranty is 2 years from the date of production.
