DC current sensors from 30A to 2000A
Packet Power offers a wide range of DC current sensors to meet your DC power monitoring needs.
- Split core CTs - 30A to 2000A
- Solid core CTs - 300A to 400A
- CTs integrated into the monitor - 35A or 65A
- 48V shunt adapters supporting existing 50mV, 100mV or 150mV output shunts at any amperage
Split core CTs
Split core CTs have a "split" in their core that allows the CT to be placed around the conductor without having to disconnect the conductor or interrupt power. Split core CTs are more expensive than solid core CTs but their convenience makes them the preferred choice for retrofit installations.
| Inside Diameter | Rated Amperage (A) |
| 16 mm | 30, 50, 100 |
| 21 mm | 100, 200, 300 |
| 35 mm | 100, 200, 300, 400, 500 |
| 42 x 13 mm | 100, 200, 300 |
| 64 x 16 mm | 200, 400 |
| 65 mm | 300, 600, 800, 1200 |
| 84 x 22 mm | 200, 300, 600, 1000 |
| 100 x 42 mm | 2000 (not pictured) |

Solid core CTs
Solid core CTs form a permanently closed core. Installing a solid core CT requires disconnecting the conductor to get it through the CT core. Solid core CTs are a cost effective solution when service disruption is not an issue and can be purchased with either rectangular or round inner openings.

Integrated CTs
The compact DC monitor with integrated CT is ideal when space is limited. The integrated solid core CT has an 8.5 mm window and supports 35A or 65A current.
Shunt Adapters
Packet Power's 48V DC monitor shunt adapters can be used with existing shunts that have output signals of 50mV, 100mV or 150mV installed on either the positive or negative leg. The adapters support shunts of any amperage.
