AC Power Architecture & Multi-Bank DC Outputs

The Phoenix Smart IP43 Charger is designed for marine craft and specialized mobile machinery requiring reliable multi-output charging. Its dual-zone casing isolates sensitive power electronics (IP43) from the lower terminal connection compartment (IP22).

The Victron Phoenix Smart IP43 Charger accepts universal 85–250 VAC (45–65Hz) and 90–375 VDC input (>0.99 power factor), utilizing a dual-zone housing with an IP43 electronics compartment and IP22 terminal strip:

• Main Battery Output: 12V (30A/50A), 24V (16A/25A), 6-Stage Adaptive Charging, Full Power to 40°C.
• Starter Trickle: 4A Auxiliary Output, Isolated Diode, 1+1 Models Only, <1mA Back Drain.
• Comms & Relays: Bluetooth BLE, VE.Direct Port, SPDT 5A Relay, Remote On/Off.

Installation & Wiring Best Practices

1. Universal Mains Input: Connect AC power to the AC mains inlet. The unit handles Nominal input voltage - AC supply 120 - 240VAC and accommodates extreme voltage drops down to Input voltage range - AC supply 85 - 250VAC (full power from 100VAC, startup from 90VAC) across Input frequency - AC supply 45 - 65Hz.
2. Service Bank Connection: Wire primary DC positive cables to the main output terminals, sizing conductors for full rated current.
3. Engine Starter Auxiliary: Connect the engine starting battery to the isolated trickle terminal (Max output current - Starter battery 4A (1+1 output models only)), keeping starting batteries charged without discharging into the house bank.

Bluetooth Configuration & Relay Automation

The Phoenix Smart IP43 Charger combines local wireless intelligence with hardware automation:

• VictronConnect Integration: Using **Data communication VE.Direct and Bluetooth (via VictronConnect app)**, technicians can adjust charge voltages, select battery chemistries, or activate low-current charging modes.
• Adaptive 6-Stage Algorithm: The Charge algorithm 6-stage adaptive (3 stage for Li-ion) algorithm cycles through bulk, absorption, recondition, float, storage, and refresh phases to maximize battery health.
• Ultra-Low Standby Drain: Disconnecting AC power leaves the charger in an ultra-low quiescent state with Back drain current <1mA.
• Programmable SPDT Relay: The built-in Programmable relay Yes (SPDT - 5A up to 250VAC / 5A up to 28VDC) can be configured to trigger remote visual alarms, audible horns, or generator auto-start contacts.
• Thermal Resilience: Designed to deliver full rated charging across Operating temperature -20 to +60°C (0 - 140°F) Full rated output up to 40°C within its Protection category Electronic components: IP43 | Connection area: IP22 enclosure.
