Single 9V DC operation Note: Measured signal must have a return (Ground) independent from power source. Ideal for use as a current meter or any application that requires measurement of a signal that is independent of the power source.

Before purchasing a pm128 pm188 lcd digital panel meter, it is essential to consider some factors. These factors include application, type of current transformers, communication setup, field configuration, and costs. There are two major types of current transformers used with panel meters; solid-core CTs and Rogowski coils. Solid core CTs are pocket-friendly and ideal in lower amperage ranges. On the other hand, Rogowski coils can handle high amperage ranges and cover a wide range of amperages with a single part number. The other factor to consider is application. You need to know the type of information you want to acquire before selecting a pm128 pm188 lcd digital panel meter. For instance, if you need a panel meter for residential purposes, a single-phase meter is ideal.

Furthermore, communication setup matters. A pm128 pm188 lcd digital panel meter can communicate through several methods. These methods include pulse, Modbus, and BACnet. If you are interested in minimum information, a pulse communication setup is ideal, but you should settle for BACnet or Modbus if you need detailed information. Another factor to consider is field configuration. A panel meter configured in the field is ideal since the preconfigured meter reduces the risk of voltage service not being covered. Lastly, it is vital to consider purchasing price, installation, maintenance, and labor costs to make sure they lie within your budget.
