I Introduction After removing the unit from its packaging and ensuring that it has suffered no damage in shipment, it is important to read this manual and follow its instructions to ensure proper connection and mounting. 700HS Series models are fully isolated dc-dc converters capable of delivering up to 850 Watts in extreme ambient temperatures and adverse operating conditions. See specification sheets at the end of this manual for the ratings of a particular model. II Installation 2.
All dimensions are in inches Figure 2 III Regulation With Remote Sense Pin G +Vo + A HS DC-DC Converter +S Load C -S twisted pair Figure 3 I -Vo The HS Series provides regulated outputs at the output terminals. When there is a large current and/or the output cable is of some length, the voltage at the end of the cable may be noticeably lower than at the terminals. The converter can compensate up to 0.75V of voltage drop through remote sense terminals.
1) To gain access, (Disconnect power from the unit before opening) remove the 5 outer black hexagonal head screws retaining the connector plate as shown in Figure #4. Then remove the 4 screws surrounding the connector. This will enable the removal of the front panel. Figure 4 2) After removing the screws, lift the panel to expose the internal components as shown.
