TDK-Lambda News

TDK Corporation announces the introduction of the ZWS240RC-24 EN 62477-1 compliant 24V 240W rated AC-DC power supply, further extending TDK-Lambda’s industrial 10W to 300W ZWS series.  This new model is certified to OVC (Over Voltage Category) III for use in fixed installations, permanently connected to the distribution panel. Applications include robotic controllers used in automotive and other manufacturing equipment requiring a higher degree of protection from input voltage transients.  OVC III compliance eliminates the need for an in-line isolation transformer, saving both cost and space.
 
Accepting a wide-range input of 85 to 265Vac, the ZWS240RC-24 can operate without forced air cooling in ambient temperatures of -10 to +70°C, derating linearly above 50°C to 30% load at 70°C.  The output is adjustable from 21.6 to 26.4V to accommodate non‑standard voltages. 
 
Typical hold-up time is 31ms, allowing the output to maintain regulation through extended input voltage dips.  The overall dimensions of this compact product are 84mm wide, 180mm in length and 42mm high.  Like other ZWS models, the ZWS240RC-24 is backed by a 5-year warranty, which demonstrates TDK-Lambda’s confidence in product reliability.
 
The unit is also safety certified to IEC/EN/UL 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.  The model meets EN 55011 and EN 55032 Class B conducted and Class A radiated emissions, EN 61000-3-2 harmonics and the IEC 61000-4 immunity standards.
