02 November 2012 High isolation switch mode power transformers unveiled High isolation switch mode power transformers unveiled The PH9185NL series of high isolation switch mode power transformers, available now from Solid State Supplies, is optimised to provide reinforced insulation power supply for RS485 and RS232 transceiver ics. 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. 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. In certain applications, such as noisy industrial environments or larger networks, peripheral devices require reinforced insulation from the network to protect them from possible interference on remote nodes. The PH9185NL series provides the needed insulation to the power driver and has a compact construction that complies with the most stringent UL and TUV standards. Pulse Electronics' PH9185NL series consists of seven turns ratios to provide the required voltage to the ic from a range of low voltage levels, delivering up to 3W of power.
