open
Remote Control Shutdown Feature (Positive Logic) remote control functions normal soft shutdown. referenced -Vin pin. With positive logic, when remote control pulled low, output turned unit goes into very input power mode. open collector switch recommended control voltage between remote control -Vin converter. remote control pulled internally, external voltage source required. user should avoid connecting resistor between remote control +Vin pin. Option "-N" Inhibit Feature (Negative Logic) This option reverses logic required Shutown. referenced -Vin pin. With negative logic, when remote control pulled low, output turned (active logic, failsafe).
user must take care ensure that reference control connected close -Vin pin. control signal must referenced ahead filtering, remotely from unit.
Typical Application
This series converters does require external components proper operation. However, distribution input voltage converter contains significant inductance, capacitor across input terminals required stabilize input voltage. minimum 1µF, quality electrolytic ceramic capacitor recommended this purpose. output decoupling recommended connect ceramic capacitor higher value directly across output pins converter. Using tantalum such series from will reduce ripple well, would perform better lower frequencies.

Safety Considerations
These converters feature 1500 Volt isolation from input output. input output resistance greater than 10M. These converters provided with Basic insulation between input output circuits according IEC60950 based standards. Nevertheless, system using converter needs receive safety agency approval, certain rules must followed design system. particular, creepage clearance requirements end-use safety requirements must observed. Please observe keep-out areas shown Mechanical Drawings. These documents include UL60950 CSA60950-00 EN60950, although specific applications have other additional requirements. order output converter considered SELV (Safety Extra Voltage) TNV-1, according IEC60950 based standards, following requirements must system design: converter internal fuse. external fuse must provided protect system from catastrophic failure. fuse with rating greater than 5.0A recommended. user select lower rating fuse based upon inrush transient maximum input current converter, which occurs minimum input voltage. Both input traces chassis ground trace applicable) must capable conducting current times value fuse without opening. fuse must placed grounded input line, any. voltage source feeding module SELV, output converter considered SELV grounded ungrounded. components converter carry transients that exceed input voltage. Even input voltage SELV (<60V) components primary side converter have considered hazardous. safety interlock needed prevent user from accessing converter while operational. 2002
