ZW40 Key benefits Predictable voltage behavior under changing load: output voltage remains linear under load for stable operation of sensitive electronics. Wide input compatibility: accepts DC 9–55 V, so it works with common 12 V and 24 V vehicle and battery systems without extra converters. High-current capability: delivers up to 40 A output to power demanding DC loads. Simple specification and integration: clear electrical limits make it straightforward to plan wiring, fusing and heat management. What it does (function) Provides a DC power output with linear behavior under load, ensuring that connected devices see consistent voltage response as current draw varies. Converts a DC input in the 9–55 V range to a controlled output while supporting output currents from 0 to 40 A. Technical specifications Product name: ZW40 Input voltage: DC 9–55 V Output current: 0–40 A Output voltage behavior: linear under load Compatibility and performance Works with a broad range of DC power sources, including 12 V and 24 V automotive, marine and battery systems. Supports high-current applications up to 40 A; plan wiring and fusing accordingly to handle the full current safely. Linear output response helps reduce voltage swings and makes performance more predictable for sensors, controllers and lighting. Practical applications (use scenarios) 1) Automotive and marine systems — power accessories and aftermarket electronics from 12 V or 24 V on-board batteries without needing separate converters, while maintaining stable voltage under varying load conditions. 2) High-current LED lighting and auxiliary loads — drive LED arrays or other high-current DC loads that require steady voltage response as brightness or load changes. 3) Battery-powered equipment and motor controllers — supply motors, pumps or power-hungry control electronics from battery packs in mobile or off-grid systems where input voltage can vary. Installation and safety notes Ensure input voltage remains within DC 9–55 V and do not exceed 40 A output. Use appropriate gauge wiring and fuses or circuit breakers sized for the expected current. Provide adequate cooling and mounting consistent with the module’s current rating to ensure reliable long-term operation. Ordering and model Model: ZW40 (specifications above).
