Power supply rectifier Siedle NG 602-01 230V → 12VAC / 23.3VDC

The Siedle NG 602-01 rectifier converts standard 230V AC mains to both 12VAC and 23.3VDC supply outputs intended for door communication and control equipment. Engineered for compatibility with Siedle systems and suitable third-party installations, this power supply provides stabilized voltages for intercom stations, call devices and access control modules where simultaneous AC and DC supplies are necessary.

Advantages

The unit supplies two regulated outputs, enabling devices that require 12VAC and others that require low-voltage DC to operate from a single mains connection. Its design supports continuous operation with stable voltage levels and reduced ripple, which helps to maintain reliable performance of audio, signalling and control circuits. Compact form and standardized input make integration into distribution or equipment cabinets straightforward.

Suitable for

• Powering Siedle intercom stations and call panels
• Supplying access control modules and electromagnetic door strikes
• Providing AC for sound/doorbell circuits and DC for electronic control units
• Retrofit or new installations requiring both 12VAC and 23.3VDC outputs

Key specifications

• Input voltage: 230 V AC mains
• AC output: 12 V AC
• DC output: 23.3 V DC
• Dual-output rectifier functionality for simultaneous AC and DC supply
• Intended for installation in equipment cabinets or wall-mounted housings

How to use

Install the rectifier in accordance with local electrical regulations and the Siedle system installation guide. Connect the 230V AC mains to the designated input terminals, observing correct phase and protective earth connections. Route the 12VAC and 23.3VDC outputs to the respective devices, ensuring polarity and voltage compatibility for DC-powered units. Verify grounding and protective devices (fuses or circuit breakers) are in place before energizing the unit, then test connected intercom and control functions to confirm correct operation.

Usage recommendations

Use appropriate overcurrent protection on the mains and output circuits, and perform initial commissioning tests with connected loads representative of normal operation. Keep the unit ventilated and avoid mounting near heat sources; follow routine inspection schedules to ensure reliable long-term performance.
