The Davicom TD-1950 is a precise sensor offering reliable detection of an audio tone of 1950Hz on a telephone line. Presence or absence of the 1950Hz tone is converted into a TTL logic level available at the OUT terminal.

The unit is AC coupled and will support any type of signal that can be found on a telephone line.

Dimensions are 103mm x 54mm x 40 mm (W x H x D), including terminal.

The ACPM-1 offers a high accuracy current measurement over a 5A to 5000A range when used with the proper SCCT Series transformer. The unit communicates over a half-duplex EIA RS-485 interface. Standard baud rates are 9,600 and 19,200 baud. The ACPM-1 uses the industry standard Modbus RTU (binary) communication protocol, allowing up to 127 units per RS-485 subnet.

Its compact size allows for installation inside most electrical service panels and junction boxes. Detachable screw terminals makes wiring easy.

NOTE: A USB-to-RS485 adapter (available here) or a MEXM-1 or -2 (available here) is required to connect an ACPM-1 to a Davicom unit.

The BPS Bidirectional RF Power Sensor can continuously monitor forward and reflected power by being permanently installed in the transmission line.

Each sensor has two internal trimmers for field calibration of the output voltages of both forward and reflected powers.

The sensor comes in two versions. Model BPS1050 has a 30-500 MHz frequency range while Model BPS5095 has a 500-950 MHz frequency range.

These sensors are perfect complements for the Davicom units, and take advantage of their pre-programmed VSWR measurement function.

LFS-1 is our 55 – 65 Hz Line Frequency Sensor to monitor power-line frequency variations in 60Hz Alternating Current (AC) Systems (95 TO 135 VAC)

LFS-2 is our 45 – 55 Hz Line Frequency Sensor.

The Line Frequency Sensor provides an analog output which is proportional to the frequency of the input source. It is normally used to monitor power-line frequency variations in Alternating Current (AC) Systems.

For readings in Hz, enter the ABC coefficients given below:

LFS-1 DV-208/216, DV-Mini, DV-Micro: A=0; B=2; C=55;
LFS-2 DV-208/216, DV-Mini, DV-Micro: A=0; B=2; C=45;

The RMSPS is a RMS RF Power Sensor designed to detect the power levels of complex RF waveforms such as DTV, CDMA and multiple transmitter signals combined onto a single antenna line for example. The power sensor is normally connected to an in-line directional coupler that allows signal sampling in both the forward and reflected directions.

The sensor comes in two versions. The Model RMSPS20 has a 20 dB RF attenuator at its input and is normally used for forward power measurements while the Model RMSPS8 has an 8 dB attenuator and is intended for reflected power measurements. Both sensors have a wide dynamic range and RF bandwidth.

These sensors are a perfect complement for the Davicom units.

The AC Current Sensor (Split-core) provides an analog DC Voltage output which is proportional to the AC current of the wire passing through it’s core. It is of the clamp-on type and therefore does not require disconnecting of the AC Power Source. It is normally used to monitor AC line current in electrical or transmission installations.

For readings in Aac , enter the ABC coefficients given below:

DV-208/216, DV-Mini and DV-Micro: A=0; B=20; C=0;

The Single-Phase AC Voltage Sensor provides an analog DC voltage output which is proportional to the AC voltage of the input source. It is normally used to monitor AC line voltage variations at remote sites.

For readings in VAC, enter the ABC coefficients given below:

DV-208/216: A=0; B=60; C=0;
DV-Mini: A=0; B=61; C=0;
DV-Micro: A=0; B=61.5; C=0;

The SCCT series of split core transformers can be installed without disconnecting the circuit being measured thus making installation easier and safer. They have a 333 mV AC full-scale output. The epoxy encapsulated housing ensures stability and long-term performance.

Models are available for 50 Amps (SCCT-1 /50), 250 Amps (SCCT-1 /250) and 1200 Amps (SCCT-1 /1200) measuring ranges. 8ft-leads are provided with the /250 and /1500 models and 3ft-leads are provided with the /50 model. See product specifications.

IMPORTANT: These current transformers are specifically designed to be used with our ACPM-1 WattNode AC Power Meter.
