Description
Trumeter CT Signal Conditioner for Current Transformer Inputs
The Trumeter CT Signal Conditioner (SC-CT-DIN) is a DIN rail-mount device that monitors AC current up to 10,000A through a current transformer. It suits switchboards and distribution panels where current is too high to measure directly, so a CT scales the reading down to a 5A input the conditioner can read. As a result, one small DIN rail unit can cover mains-level current monitoring.
- Monitors AC Currents up to 10,000A via CT
- High-Resolution 5A Input for 0.5% Accuracy
- Dual Outputs Configurable as Digital (Open Collector) or Analog (4-20mA)
- 10 Alarm Setpoints with Configurable Output Delays
- 20-Point Non-Linearization Scaling for Non-Linear Sensors
- 16 Pre-Set Configurations for Faster Commissioning
Because the scale and range are configurable in software, the same SC-CT-DIN can be matched to whatever CT ratio is already installed on site. Therefore, it drops into existing switchboards without re-specifying the current transformer. For DC current measured through a shunt, use the Shunt Signal Conditioner instead.
Configuration and Installation
The unit clips onto standard Top Hat Slotted (TS35) DIN rail and measures 72mm x 72mm x 61mm. It runs from a 12-24V AC/DC supply, and setup is handled through Trumeter’s free configuration software over USB, with 16 pre-set configurations available to speed up commissioning on common CT ratios.
The unit carries CE, cUL, UL, RoHS, and IP20 ratings, covering most industrial and OEM panel-building requirements without extra certification paperwork.
