Power Series Plus: 3 in 1 AC Volt /Amp/Hertz

A versatile AC Digital Power Meter

3 in 1

The POWER SERIES Plus digital switchboard meter was developed by Yokogawa Corporation of America to provide our customers with a versatile AC digital power meter. The heart of our POWER SERIES Plus meter is a programmable ASIC Power Measurement Chip (PMC) which was jointly developed by the General Electric Company and Yokogawa Electric Corporation. This unique PMC capability will continue to expand into many new power measurement and control products offered by Yokogawa Corporation of America. The design of the POWER SERIESPlus combines a high accuracy digital switchboard meter with transducer output which can be configured in the field by an end-user, or when installed in new electrical equipment by an OEM. It eliminates requirements for a large inventory of dedicated instruments, and provides flexibility when new panel designs or system upgrades require changes in instrument transformer ratings. Our rugged metal case fits standard panel cutouts for switchboard meters and makes it a perfect replacement for less versatile instruments. The RS-485 communications option allows up to 32 meters to be networked together for remote monitoring and control. In addition, the POWER SERIESPlus can be set up and locked out for security via the remote communications option.

The NEW 2493 triple display multifunction power meter . . .
Ideally designed for easy retrofit into existing switchboard meter panel cutouts. The 2493 features three easy to read LED displays, minimum/maximum values at the touch of a button, scaling up to 1250:1 for potential transformers and 5000:1 for current transformers. Optional 0-1mA DC and 4-20mA DC analog outputs are configurable by the user and RS485 communications option is available at no additional cost. The 2493 is also available with a wide choice of power supply options.

Quick Specs

• Scaling of the instrument for PT (potential transformer) primary ratings up to 1250:1; and CT (current transformer) primary ratings up to 5000:1.

• Adjustable transducer output proportionate to the primary input setting.

• Electrical legends (i.e., Watts, Kilowatts, Megawatts) can be set by the user and indicated by a red LED adjacent to the selected legend.

• Display average setting: Adjustable to obtain a “rolling average” of inputs. Increasing the number of samples reduces annoying “digit bounce” by the least significant digit.

• All settings are stored in non-volatile memory. If there is a loss of power to the instrument, all settings will remain as they were prior to power loss.

• Accuracy of ±0.2% of reading, ± 0.1% of full scale.

• True RMS current and voltage measuring capability. A most desirable feature when distorted wave forms are present on the line.

• High resolution/ high intensity LED displays that can be viewed from almost any angle.
