(ZVS) inverter which permits very high frequency conversion with minimum losses. As a laser diode driver, the LDD-3000 power supply acts as a current source and delivers constant current based on the input program signal, Iprogram(+), which is normally 0-10V. An optional RS-232 interface is available. All units are configured with a maximum current and maximum voltage capability, depending on the user’s requirements. -

Page 12: Installation And Operation
Installation and Operation of LDD-3000 Diode Drivers There are two 8-32 PEM nuts on each side of the LDD-3000 for mounting the unit in a system. Refer to Figure 2, the LDD-3000 Outline Drawing, for the location of these PEM nuts Also, there are four 10-32 PEM nuts on the bottom of the chassis for mounting purposes. - Page 13 Power can provide any assistance necessary to modify interface program and monitor levels) See Table 1 and Figure 3 for description of LDD-3000 Interface and the associated simplified interface schematic. IMPORTANT NOTE Make sure when connecting interface that the current program setting, Iprogram(+), is set no higher then the value required for operation.
