![]() Elation is breaking new ground in hybrid performance with patent-pending optical systems. Who knows the power supply may come back to life again. We pride ourselves on being at the forefront of lighting innovation. If you have test all the components in the power supply section and still could not find out the fault, i guess there is no harm in replacing the IC and retest it again. What about Optoisolator IC that breakdown when under load? Yes in my repairing career i do came across Optoisolator IC that breaks down when under full operating voltage but it was rare too. We cant see inside but the optical isolation with sfp modules already had swallowed all the digital network chain. In addition, each output has dedicated drivers to boost. This unit takes the incoming DMX signal and splits it to four (4) separate outputs that are electronically isolated from each other to ensure uninterrupted data. This unit takes the incoming DMX signal and splits it to eight (8) separate outputs, each providing a total electrical isolation of up to 1000V between different branches in a daisy chain group. The OPTO BRANCH 4 is a single rack space, 4-way distributor/booster with locking 3/5pin XLR Connector input and output jacks. Since this IC is not difficult to test, i suggest that if you come across problem with the power supply with the symptoms that i have mention above, you may check on the Optoisolator IC first. The Elation Pro Lighting OPTO BRANCH 8 is a 19' single rack space, 8-way DMX distributor/booster with 5-pin XLR input and output jacks. This greatly decreases problems with ground loops and efficiently. This unit takes the incoming DMX signal and splits it to eight 8 separate outputs, each providing a total electrical isolation of up to 1000V between different branches in a daisy chain group. In power supply, if the Optoisolator have problem it will cause many different types of symptom like no power, low power or even power shutdown. The OPTO BRANCH 8 is a 19 single rack space, 8-way DMX distributor/booster with locking 5pin XLR DMX input and output jacks. However, digital isolators cannow provide a cost-competitive, easy-to-implement,and higher-performance solution, all in a small formfactor. The LED diode inside the Optoisolator IC rarely have problem and you can test it using analog meter set to X 1 Ohm and it should have one reading. Optocouplers only remain apopular option when isolating digital interfaces dueto their low cost. The second circuit is doing 'high side switching' and should be done with PNP optocouplers. If there are two readings then it is either consider shorted or leaky. Simply, the transistors in the optocouplers are NPN, so should be used for 'low side switching'. ![]() The most common fault for an Optoisolator IC is the short circuit between the collector and the emitter pin and you can test it by using an analog meter set to X 10 K ohm and it should not show two readings. ![]()
