Page 3: Introduction
Solar panel voltages up to 42V can be connected. In addition to the alternator and solar inputs, the NLDC-40 features a dynamic DC power input that accepts DC voltages from 11V to 32V. An advanced load-response algorithm is used to support DC sources with variable power levels. This allows alternative energy sources such as AC-DC power supplies, wind generators or DC generators to be used. -

Page 5: Preparing For Installation
The NLDC-40 should be located close to the auxiliary battery for best voltage regulation. Ÿ The NLDC-40 can operate in harsh environments but it is best installed in a location that is cooler with adequate ventilation. Ÿ Avoid areas exposed to harsh or corrosive chemicals, excessive dust, extreme heat or mechanical movement. -
Page 6: Fitting The Nldc-40
Fitting the NLDC-40 The NLDC-40 has 4 mounting feet, use these to attach the NLDC-40 to a secure, flat surface. Use appropriate screws or bolts to attach the NLDC-40 securely, M4 machine bolts are recommended. DO NOT drill into or modify the NLDC-40 housing. - Page 7 Use appropriate fasteners to secure the assembled plate to the application. The NLDC-40 can be rotated on the plate by 180° to suit the application. Two sets of threaded holes are provided on the plate to...

Page 8: Dc Input
It is recommended to install a fuse in-line with the DC power source. The current rating of this fuse should be higher than the DC source maximum current but no more than 50A. With a suitable power supply, the NLDC-40 will act as a battery charger. Do not use the output from a stand-alone battery charger as the input to the NLDC-40. -
Page 9: Solar Input
Solar Input The NLDC-40 features a built-in 600W MPPT (maximum power-point tracking) solar regulator with 40A output current and support for panels up to 42V. The MPPT algorithm ensures that the maximum power available from the connected solar panels is fully utilised under varying conditions and converted into maximum output charge current. -

Page 13: Remote Monitor
Remote monitor - (Optional accessory) The Remote Monitor for the NLDC-40 provides status information about the system and batteries on a high-contrast LCD screen. Information such as Main and Auxiliary battery voltages, charge mode, charge current, battery type, battery temperature and error conditions are displayed on a choice of 3 user-selectable display modes. -
Page 14: Remote Monitor Operation
Remote Monitor operation The remote monitor can be turned ON or OFF by pressing the POWER button. The display will turn off automatically after a short delay if there is no active charge cycle. The display brightness can be increased or decreased by pressing the UP or DOWN buttons. The remote monitor has 3 display modes that represent the status of the charging system in different ways. -
Page 15: Remote Monitor Warning Messages
It is possible that the battery is damaged or is located in an area that is too hot. This error will also be displayed if the NLDC-40 temperature is above 115°C. Charge will stop until the system temperature drops to a safe level. -
Page 16: Application Examples
Application examples Installation in a Trailer or Caravan The NLDC-40 can be installed in a Trailer or Caravan that is equipped with batteries. In this application, the NLDC-40 supports a stand-alone application with solar input as well as a removable connection to the charging system of the towing vehicle. - Page 17 The NLDC-40 will regulate the output current based on the limitations of the DC supply. This prevents over-loading of the supply. FUSE In order to benefit from the full 40A capability of the NLDC-40, a 600W FUSE DC source is recommended with a voltage in the range of 11V - 32V.
- Page 18 Any loads connected to the battery will be powered by the NLDC-40 when a charge cycle is active. If the Auxiliary Battery Box is disconnected, the NLDC-40 will automatically revert to a safe mode. An error will appear on the...
