| Description
The HT Instruments HT903 is an accessory board used to connect external current transformers (CTs) to multi-function meters, power quality analyzers, and other compatible instruments. It enables the measurement of very high currents, which are beyond the limits of a standard meter's clamps. |
| Key Features
Input: Receives signals from external CTs with either a 1A or 5A secondary current ratio. Output: Converts the input signal to a 1V AC output signal for connection to an analyzer. Voltage category: CAT II 300V. Working temperature: 14°F to 122°F (-10°C to 50°C). Storage temperature: 14°F to 140°F (-10°C to 60°C). Weight: Approximately 5.51 lbs (~2.5 kg). Dimensions (L x W x D): 250 x 105 x 130 mm. |
