Page 3: Low Voltage Disconnect And Reset
The LVD voltage and the LVD Hysterisis voltage are preset in the factory, but may be adjusted to suit the specific battery installation - see Section 4.7. Model Voltage Adjustment Maximum Load Current SPS 12-20 9.5 to 12V SPS 24-10 19 to 24V SPS 48-6 38 to 38V Do not exceed the maximum load current, as the LVD circuitry may be damaged. -
Page 4: Output Over Voltage Shut Down
Output Over Voltage Shut Down The SPS will automatically shutdown if the output voltage exceeds the preset value. The Over Voltage Shutdown voltage is preset in the factory but may be adjusted. Input Over Voltage Shut Down If the input voltage is outside the specified range, the SPS may shut down until the allowed voltage is restored. 1.10 Input Inrush Current Limiter On startup, the peak AC inrush current is limited to twice the maximum operating current. -
Page 5: Internal Alarm Card
• Low voltage output When SPSs are connected in parallel using an RJ45 patch cable (Newmar part # 466-4524-0) to connect between the alarm and control interface on each rectifier, the alarm outputs on the Alarm Card give the status of all the connected units. -
Page 6: Cabling
Caution: The rectifier must be mounted on a vertical surface so that it stands vertically, and is not laid flat on its side. Observe orientation arrow printed on front panel. Do not mount rectifiers above each other. Cabling It is important that all cables (except AC) are less than 10 feet in length. The rectifier is not designed for cables greater than 10 feet or for connection to outside cables. -
Page 7: Temperature Compensation
If the LVD functionality is not required, the load must still be connected to the Load connection (not directly onto the battery). It is recommended that two wires are run in parallel for both the +v and –v Battery and Load connections. 14 AWG wire should be used for the connectors. -
Page 8: Relays
When units are connected in parallel using an RJ45 cable to connect between the alarm and control interface, the alarm outputs on the Alarm Card give the status of all the connected units. This means that you only need one alarm card connected to the external alarm circuitry when the units are connected in parallel. The diagram on the following page describes the alarm contacts found on the right side of the unit. -
Page 9: Rectifiers In Parallel
The internal alarm cards of multiple parallel units can be connected in parallel (using RJ45 Cat. 5 style patch cord, Newmar part # 466-2524-0, 24” length) so that the alarm condition can be reported if any alarm is triggered in any SPS. -

The SPS must be disconnected from the battery and load. The adjustment trimpots are accessible on the rear side of the rectifier, with the AC input oriented to the left, the trimpots read as follows. 4.1 Standard Settings Item SPS 12-20 SPS 24-10 SPS 48-6 Boost Voltage 14.2V... -
Page 12: Adjust Boost To Float Current Threshold
Adjust Boost to Float Current Threshold Connect a variable load (set to minimum load) to the battery connections of the SPS. Disconnect the Temperature Compensation Probe. Connect an accurate current meter in series with the load. Turn on AC to the unit, wait 10 seconds and then adjust the load up slowly until the unit goes into Boost Charge mode (as indicated on the LEDs). -
