Solid State Supplies announces availability of the PH9185NL series of high isolation switch mode power transformers from Pulse Electronics. The transformers provide a reinforced insulation power supply for RS485 and RS232 transceiver ICs and are designed on an SMD platform with offset pins to maintain a large separation between primary and secondary circuits. Applications include industrial control systems, building automation, smart grid, surveillance, and aeronautics. The Pulse Electronics PH9185NL transformers facilitate using a RS485/232 communications bus as a low cost alternative to Ethernet. They are compatible with the Maxim MAX253 power driver IC. In accordance with IEC60950/EN61558, the construction of the PH9185NL series has been certified by UL/TUV for reinforced insulation up to a 400V working voltage. The design guarantees 8mm creepage and 4000Vrms isolation voltage to meet this requirement. The design also utilizes Pulse Electronics’ Class F insulation system. In certain applications, such as noisy industrial environments or larger…
