MORNSUN 3W AC-DC power supply Integrated isolated RS485-TLAxx-03K485 - 1

3W AC-DC power supply Integrated isolated RS-485 FEATURES • Universal 85 - 305V AC and wide 100 - 430V DC input voltage range • Accepts AC and/or DC input (dual-use of same terminal) • I/O isolation test voltage of 4000VAC • Output short circuit and overcurrent protection • High baud rate up to 500kbps • Bus supports up to 128 nodes maximum • Compact open frame design with high power density • Flexible design of peripheral circuit reduces layout issues TLAxx-03K485 series are 3W AC-DC power converters with integrated., isolated RS-485. The products can directly be connected to commercial 220V AC power sources. The main DC power output of the supply is 25W and the auxiliary DC power output is used for bus communication. They feature a very high isolation test voltage of4000VAC between AC input and each of the two DC power outputs., and 1500VDC in between the two DC power outputs. The products are widely used in industrial and electrical instrumentation and similar demanding applications for Digital communications networks requiring wide input voltage ranges., a completely isolated bus and compliance to UL/CE safety and EMC standards. For applications in extremely harsh EMC environment., we recommend using the application circuit show in Design Reference of this datasheet.

2. EMC solution-recommended circuit Component As the modules internal A / B lines come with its own ESD protection, which generally satisfy most application environments without the need for additional ESD protection devices, as shown in the typical circuit in Figure 1. For harsh and noisy application environments such as motors, high voltage/current switches, lightning and similar however, we recommended that the user protects the module's A / B lines with additional measures and external components such as TVS tube, common mode inductors, Gas discharge tube, shielded twisted pair of wires...
