DIN Rail Power Network Analyzers

A DIN rail power network analyzer is a multifunction measuring instrument that clips onto a 35 mm mounting rail without needing a cutout in the panel door and measures current, voltage, power, power factor and energy values. It is used in sub-panels with no room on the door, in machine panels, and at energy monitoring points where values are read over communication rather than from a display. Most of the category consists of the Entes MPR and EPM series, and the Tense TPM-04SHDL is also in this group; there are models with supply voltages specified as 95-270 V AC/DC, 110-230 V AC, 12-50 V DC and 10-56 V DC. Choose the supply voltage by the auxiliary voltage in the panel (AC or DC), the communication by the monitoring system, the harmonic measurement and the number of inputs and outputs by need, and the housing width by the free space on the rail. The Tense model's product data specifies RS-485 communication, a relay output and a digital input. A DIN rail analyzer should not be confused with a rail-mounted energy meter that only counts kWh; in addition to energy, the analyzer also measures current, voltage, power and power factor.

How to choose DIN Rail Power Network Analyzers

A DIN rail power network analyzer is a multifunction measuring instrument that clips onto a 35 mm mounting rail without needing a cutout in the panel door and measures current, voltage, power, power factor and energy values. It is used in sub-panels with no room on the door, in machine panels, and at energy monitoring points where values are read over communication rather than from a display.

  • Take reactive power demand and harmonic distortion levels from site measurements or project calculations.
  • Compare kVAr step sizes, rated voltage and step count against the compensation panel layout.
  • Select capacitor duty contactors, harmonic filter reactors and discharge resistors together with the capacitor bank.
