NPDC25- PROJECTA 25A 3 Stage Switch mode DC-DC & Solar Battery Charger

Allows you to charge your 12V second/auxiliary deep cycle battery on the go, simultaneously from solar and alternator (9-32V) inputs. PDC25 is shock, vibration and dust proof.

FEATURES The PDC25 DC-DC charger is purposely designed for charging 12V auxiliary batteries from 12-24V vehicles. It includes all the features needed to maintain the auxiliary battery to its optimum condition and to prolong the battery life.

SWITCHMODE TECHNOLOGY The PDC25 converts your vehicle’s 12VDC/24VDC alternator power to the required voltage level allowing your batteries to be fully charged, prolonging battery life and reliability. With the latest synchronous switching technology, efficiency of PDC25 exceeds 94% at full load condition.

DUAL INPUT OPERATION Allows two energy sources to power the PDC25 simultaneously. Solar input takes precedence if solar and alternator inputs are present. When solar input cannot provide enough energy to the load, the PDC25 will draw power from solar and the alternator simultaneously.

SOLAR MPPT The PDC25 utilises sophisticated MPPT (Maximum Power Point Tracking) solar regulator technology. MPPT maximises the power generated from the solar panels to the auxiliary battery.

SUPERIOR 3 STAGE CHARGING 2 Using high speed microcontroller and proprietary charging algorithm, the PDC25 delivers a sophisticated 3 stage charging process resulting in a faster and more powerful charge, ideal for deep cycle batteries. The first stage, bulk (constant current), charges the battery faster while the second stage, absorption (constant voltage), ensures the battery is thoroughly charged. The final stage, float, maintains the battery at a safe voltage allowing it to be maintained and ready for use indefinitely.

MULTI-CHEMISTRY SUPPORT The PDC25 supports Lithium , AGM, WET and CALCIUM batteries. If the calcium battery mode is selected, periodic equalisation will be provided to the calcium battery for removing acid stratification.

IGNITION CONNECTION The ignition connection activates the lower input voltage operation to suit vehicles with smart (variable voltage) alternators. For vehicles without a smart alternator, no ignition wire sensing is required.

VOLTAGE DROP COMPENSATION The PDC25 overcomes the problem of voltage drop associated with long cables commonly used with input and auxiliary battery installations. By ‘stepping up’ the dropped voltage using switch mode technology, the PDC25 delivers a full three stage charge to your auxiliary battery.

TEMPERATURE COMPENSATION The PDC25 is supplied with a 2 metre temperature sensor. The sensor monitors the battery temperature and adjusts (compensates) the charger’s output to prevent overcharging. This is ideal for batteries used in warmer climates or environments.

REMOTE CHARGER STATUS INDICATION A pink wire is provided for driving an external panel mount LED indicator (Eg Narva P/No. 62090BL) to show the status of the charger. It shows whether the auxiliary battery is on charge (Solid Colour) or the charger is in a fault condition (Flashing). 

PROTECTIVE FEATURES

Spark-Free Protection The PDC25 will not start charging the battery (no output) unless the load is securely connected. It prevents the output leads from sparking due to accidental short circuit making the charger safer to use around batteries.

Reverse Connection Protection Reverse connection on input and output terminals does not damage PDC25 internal circuit. The PDC25 detects reverse connection condition and indicates whether input or output connection is reversed.

Over and Under Voltage Protection The charger will automatically shut down if there is an over voltage or under voltage problem.

Over Temperature Protection The charger will lower its output current if the temperature of the unit begins to overheat.
