| Series Features |
| 350 SERIES - 3-phase voltage/phase monitor |
| Series Description: The 350 series is a heavy-duty voltage monitor. This product should be used when high current relays or dual contacts are required, or 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 model 250. The 350200 has a 15 A general purpose contact. The 350400 provides a SPDT (Form C) relay rated to switch up to 600 V, allowing the use of 480 V controls, eliminating the need for a control power transformer to step the voltage down to 120240 V. Several DPDT (two Form C contacts) relay models are also available. The 350 microcontroller-based family of products are low cost yet highly advanced solutions to heavy-duty problems. The 350 includes advanced single LED diagnostics. Five different light patterns distinguish faults and normal operating conditions. Other options such as high voltage trip and adjustable restart delay are available. |
