To maintain the specified +\/- 1% regulation, the power supply utilizes internal feedback loops to compensate for variations in line voltage. The 24 VDC output is maintained with low ripple characteristics, facilitating stable operation for sensitive analog input and output modules within the YOKOGAWA ecosystem. Proper thermal management via the integrated forced-air cooling fan is required to prevent derating when operating at ambient temperatures approaching 50 deg C.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: What are the constraints regarding the forced-air cooling system?\u003c\/p\u003e\n\u003cp\u003eA: The PW502\/S1 utilizes an internal fan for heat dissipation. Users must ensure a minimum clearance of 50 mm above and below the module to prevent obstruction of the airflow path and ensure thermal stability.\u003c\/p\u003e\n\u003cp\u003eQ: Is this power supply capable of parallel operation to increase total output current?\u003c\/p\u003e\n\u003cp\u003eA: The standard configuration for the PW502\/S1 is designed for dedicated load requirements. Parallel wiring to increase output current is not supported unless external decoupling diodes are utilized to prevent back-feeding and current imbalance.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the module vertically on a standard industrial DIN rail to ensure optimal airflow through the internal heat sink assembly.\u003c\/li\u003e\n\u003cli\u003eEnsure the protective earth (PE) terminal is connected to a low-impedance ground point to minimize common-mode noise on the 24 VDC output rail.\u003c\/li\u003e\n\u003cli\u003eUse shielded, twisted-pair cabling for DC output distribution to mitigate electromagnetic interference (EMI) in high-density DCS cabinets.\u003c\/li\u003e\n\u003cli\u003eVerify that the input AC supply is protected by a suitable circuit breaker or fuse rated for 100-240 VAC operation prior to initial power-up.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49134186037500,"sku":"PW502\/S1","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/PW502S12.jpg?v=1779760807","url":"https:\/\/www.electronicplc.com\/ar\/products\/pw502-s1-yokogawa-power-supply-unit-new-original-stock","provider":"Electronic PLC","version":"1.0","type":"link"}
