ValueLine IPC Warranty Extension
Reducing susceptibility to surges is crucial for increasing uptime and extending the life expectancy of the ValueLine IPC and its power supply. Phoenix Contact's surge suppression protects these devices from damaging surges, protecting your investment.
Testing Surge Protection to IE/ANSI C37.90.1 -2002
In 2002, the IEEE/ANSI C37.90.1 and IEC 61000-4-18 standards were harmonized and the resulting differences are very small. For this paper we used text from the IEC standards to clarify the testing of surge protective devices (SPD).
The industry standard for surge protection is UL 1449 (ANSI/UL 1449-2006). Every few years the standard is revised, reflecting best practices for safety. On September 29, 2009 the new, 3rd edition of UL 1449 went into effect.
Surge Protection for DeviceNet™ Networks
The MCR-PLUGTRAB PT consists of a header (PT PE/S+1x2-BE) and a plug (PT PE/S+1x2-24-ST). The header (base unit) attaches to standard DIN rail, and the replaceable plug fits into the header.
Power Supply Warranty Extension: Extending Power Supply Warranty to 5 Years Unconditional
Increasing uptime begins with a high-quality power supply from Phoenix Contact. Reducing vulnerability to surges further increases uptime and extends the life expectancy of the power supply.
