美国vanguard RFD-200 S3数字计时器Digital Timer
The RFD-200 S3 is a portable relay test set that delivers performance verification testing of electromechanical, electronic, and microprocessor-based protective relays in their operating installations. The RFD-200 S3 is a rugged test set suitable for testing a variety of protection relays operated in both indoor and outdoor environments. The unit’s ergonomic design and intuitive control panel layout make it ideal for first-time users who have little or no training.
A built-in Timer displays contact time in both cycles and milliseconds
AC current source with 3 outputs (10A, 40A, 100A)
Set of NO/NC dry contacts that change state when a test is initiated
AC voltage source for testing relays up to 250 Vac
DC Voltage source (0 - 300 Vdc)
Volt meter input (0 - 600 V input range)
Three power supplies (24 Vdc, 48 Vdc, 124 Vdc)
