MikroTik APA-1 Automotive Power Adapter 12-48V 100W

The MikroTik APA-1 is an automotive-grade DC power adapter engineered to shield connected devices from the harsh and unpredictable electrical conditions found in vehicle environments. Drawing on a layered defense architecture, it combines a Gas-Discharge Tube, Transient Voltage Suppressor, Active Polarity Protection, Low-Pass Filter, and a standard fuse to guard against voltage spikes, transient surges, reverse polarity, and electrical noise generated by events such as jump-starting, failed batteries, harness coupling, and AC unit switching. Rated for a wide input range of 12 V to 48 V and a maximum load of 100 W, the APA-1 accommodates a broad spectrum of vehicle electrical systems. Output voltage is user-adjustable via jumper position, with a pass-through mode available when direct input voltage regulation is preferred. E-Mark certified and compliant with CE, EAC, and RoHS standards, the adapter meets stringent automotive homologation requirements. Its IP20-rated, passively cooled enclosure is suitable for both indoor and outdoor installations, and it is compatible with the GPER IP67 case for deployments requiring additional environmental protection. The operating temperature range of -40 °C to +85 °C makes it well suited for extreme climates and demanding mobile infrastructure deployments.

Key features & benefits

• Gas-Discharge Tube Protection — Ionizes gas within a sealed glass tube to create a low-resistance discharge path, diverting dangerously high voltage away from connected equipment before it can cause harm.
• Transient Voltage Suppressor (TVS) — A semiconductor-based clamping device that responds rapidly to extreme voltage spikes, providing a secondary layer of overvoltage defense beyond the Gas-Discharge Tube.
• Active Polarity Protection — Electronically prevents damage if DC power is applied with reversed polarity, eliminating a common installation error that can instantly destroy unprotected equipment.
• Low-Pass Filter — Attenuates high-frequency electrical noise and unwanted impulses on the power line, ensuring clean, stable DC power reaches the downstream device.
• Standard Fuse — Provides a final overcurrent protection barrier, interrupting the circuit under fault conditions to safeguard both the adapter and connected devices.
• Adjustable Output Voltage via Jumper — Output voltage can be reconfigured by changing the jumper position, with a pass-through mode available to deliver the raw input voltage directly to the load.
• Wide Input Voltage Range — Accepts 12 V to 48 V DC input, making the APA-1 compatible with a variety of vehicle and stationary power sources up to a maximum load of 100 W.
• E-Mark Certification — Certified to the E-Mark automotive standard, confirming the adapter meets rigorous electromagnetic and safety requirements mandated for in-vehicle electronic components.
• Extreme Temperature Operation — Passive cooling and an operating range of -40 °C to +85 °C ensure reliable function in arctic cold, desert heat, and everything in between without need for a fan or active thermal management.
