美國(guó)vanguard RFD-200 S3數(shù)字計(jì)時(shí)器

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)
• Built-in power resistors
