Efficient and Protected 12 V DC Power for Industrial Control Systems
The Finder 78.36.1.230.1202 converts a compatible AC or DC supply into a regulated low-voltage DC output using high-frequency switch mode technology. Its flyback converter incorporates quasi-resonant zero-voltage switching to support efficient power conversion. The integrated potentiometer allows the output to be adjusted from 12 to 16 V DC, enabling the supply to be configured for compatible equipment within its electrical operating limits.
To support dependable operation, the unit includes an integrated input fuse, varistor protection, internal thermal protection and hiccup-mode short-circuit protection. During a short circuit, hiccup protection periodically attempts recovery rather than continuously delivering excessive fault current. The power supply also supports suitable redundant arrangements using external OR-ing diodes and may be used in compatible battery-charging applications where the manufacturer's voltage, current and battery requirements are satisfied.
Typical Applications
- Industrial automation and electrical control panels.
- 12 V DC electronic control circuits.
- Industrial sensors and monitoring equipment.
- Control relays and compatible low-voltage devices.
- Building automation and access control systems.
- Security and CCTV equipment requiring a compatible 12 V DC supply.
- OEM machinery and industrial electronic assemblies.
- Low-voltage signalling and indication systems.
- Compatible lead-acid battery charging and backup power arrangements.
- DIN-rail-mounted power distribution within electrical enclosures.
