Split Core Current Sensor with 5VDC output
- July 28, 2023
- 0 Comment(s)
These split core current sensors are cost-effective tools for monitoring single phase AC loads such as fans, pumps, and compressors. The split core design and the self powered electronics make for very simple installation. They are suitable for general monitoring and alarming of HVAC systems for conditions such as a slipped belt or an impending bearing failure.
Split core Current Transformer, 5A output
- May 17, 2016
- 0 Comment(s)
The split core current transformer are used for monitoring power of large electrical loads and electrical services. Current flowing in the primary conductor creates a proportional current in the secondary output coil with a range of 0 to 5 amps. This is typically used to drive current indicators on large electrical panels. It is also compatible with commonly used power meters in the industry such as our Three Phase Power Meter.
are ideal where space is limited, such as when metering multiple loads within a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and submetering applications.

Featuring top-mounted terminals, this enclosed power relay has a flange-type mounting bracket for mounting in panels and ductwork. These relays are good as status points for high voltage circuits, connect the coil to the high voltage equipment and wire the dry contacts directly into the low voltage side of any of the controllers and thermostats on this site. The spade terminals make for easy troubleshooting in the field and good isolation of high & low voltage circuits.
High power switching capacity for motors and other inductive loads. The standard stocking item is the 20 amp version though we have 30 and 40 amp available as well as other variations shown in the datasheet, by request.

- 0 Comment(s)
This sensor is used to measure the outside air temperature to allow the DDC system to coordinate the mechanical systems with actual building load conditions, enabling such strategies as free cooling, optimum start/stop, and supply temperature reset. The housing is made from PVC and stainless steel fittings which shield the probe from direct sunlight. There are three thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.
