DHA52 is a fully programmable timer to allow execution of self-designed timing functions. The function can be prepared using the free PC software BHF and connecting the unit to a PC. The user can decide to leave to the front knob for final setting the adjustment of one of the time steps. For mounting on DIN-rail. 17.5 mm wide housing suit- able both for back and front panel mounting.

This document describes the features and characteristics of the DIA53 monitoring relays, including 2-wire connection, self-powered, input ranges, adjustable set-point, and output.

DWB01 and PWB01 are precise TRMS power factor monitoring relays for 3-phase balanced systems. They can be used for monitoring the actual load of asynchronous motors and other symmetrical loads, where the power factor is almost proportional to the load. The relay measures the power factor (cos ϕ), that is the ratio between the active and the apparent power of a motor. Start/stop input allows to use a manual switch to start and stop the motor, without the need of an auxiliary device. The advantage of using the latch function is that the relay can be kept energized even after the end of the alarm condition. Inhibit function can be used to avoid relay operation when not desired (maintenance, transients). The LED's indicate the state of the relay, alarm, and power supply.

This document describes a small, low-cost mono function timer with adjustable time setting. It has only 2-wire connection for easy and fail-safe use. The timer is used to delay small industrial relays or 3-phase contactors. It can be mounted on DIN-rail or directly on surface by screws.

The document describes a multifunction timer with 7 knob selectable functions and 7 knob selectable time ranges. The timer operates within a time range of 0.1s to 100h and has adjustable time settings through knobs and external adjustment. It offers high repeatability and can be powered by different voltage supplies. The timer is designed for mounting on DIN-rail or plug-in, providing flexibility in installation.

Multi-function timer DMB01, PMB01 has 7 knob selectable functions and 7 knob selectable time ranges within 0.1s and 100h. Can be mounted on DIN-rail (DMB01) or Plug-in (PMB01).

WM14-96 is a 3-phase power analyzer with built-in programming key-pad. Particularly recommended for displaying the main electrical variables. Housing for panel mounting, (front) protection degree IP65, and optional RS485 serial port or dual pulse out- put. Parameters pro- grammable by means of CptBSoft.

The document describes a 3-phase multifunction power indicator with high accuracy, various display functions, and multiple measurement parameters, suitable for displaying the main electrical variables.

This product is a 3-phase multifunction power indicator with built-in programming keypad. It is particularly recommended for displaying the main electrical variables. Housing for panel mounting, (front) protection degree IP65 as standard, and optional RS485 serial output.

The product is a multifunctional power analyzer with single phase and three phase instantaneous variable measurement functions, including W, Wdmd, var, vardmd, VA, VAdmd, PF, PFavg, V, AL, An, Hz, THD (maximum and minimum values for all measurements); measured energies include kWh and kvarh (4 quadrants); load curve can be displayed graphically (daily, weekly, monthly display).

This is a smart power quality analyzer that measures single-phase and three-phase system variables (W, Wdmd, var, VA, VAdmd, PF, PFavg, V, A, An dmd). It has a graphical display, 4x4-bit instantaneous variable readout, 4x9-digit total energy readout, 4x6-digit partial energy readout, 48 independent energy meters to be used as single, dual, multi-time energy management.

This product is a µP-based indicator with manual or automatic scrolling of system and single phase functions, which can measure kW, kVAr, PF, kWh, kVArh, I, V∆avg, VL1-N, VL2-N, VL3-N. It can also measure distorted waves (voltage/current) of TRMS, select all configuration functions by the built-in keypad, and protect programming parameters with passwords. The front protection level is IP 40, and it has standard pulse output and optional serial RS 422/485 output, supporting MODBUS and JBUS protocols.

The WM1-DIN27AAD0XX is a 3-digit multi-range microprocessor meter produced by WEG Germany. It has the scrolling display function of power, energy, power factor (cos ϕ), current and voltage, and can automatically select the k (kilo) or M (mega) scale. It also has the function of automatic peak value measurement, and has dual measurement inputs: 5A or 27A. In addition, the housing of this meter is easy to mount on a DIN rail and offers an IP40 protection rating.
