The 350 series is a heavy-duty voltage monitor. This product should be used when high-current relays or dual contacts are required or when 480 V controls are used. Since the 350 series uses heavy-duty relays, it comes in fixed-voltage range models rather than a dual, auto-ranging version like the 250 model. The 350 microcontroller-based family of products offers highly advanced solutions to heavy-duty problems at a low cost. This series includes advanced single LED diagnostics with five different light patterns to distinguish faults and normal operating conditions. Other options such as high-voltage trip and adjustable restart delay are also available.

Series 350 models include the 350-200, which has a 15 A general purpose contact. The 350-400 provides an SPDT (Form C) relay rated to switch up to 600 V, allowing the use of 480 V controls and eliminating the need for a control power transformer to step the voltage down to 120-240 V. Several DPDT (two Form C contacts) relay models are also available.

Eigenschaften

  • Proprietary microcontroller-based circuitry
  • Adjustable restart delay (-2 models) settings
  • Advanced LED indication
  • 600 V rated relay contacts available on some models
