1. Overview

2-way Power Supply System

The SIR-3000 series can run on AC 100/120 V (allowable range 90 to 132 V) or AC 220/240 V (allowable range 198 to 250 V), or DC 12 V (allowable range 11 to 30 V) supplied externally. The recording unit also includes a dedicated nickel-hydride battery pack for smooth, uninterrupted operation if the power is suddenly cut off.

The unit automatically switches to the power supply in the following order of priority: 1AC, 2 DC, 3 internal backup battery.

If the AC source is cut off, the external DC or internal backup battery provides uninterrupted backup. If the external DC source is cut off, the internal backup battery provides uninterrupted backup. The SIR-3000 series cannot operate on the battery only. The internal backup battery is used to protect the recording media when the power failure occurs. When the backup operation continues for 3 minutes or longer, the unit is shut down.

The internal backup battery is recharged automatically, but note that it may not be charged in the cases shown below based on the power switch setting or power supply conditions.

Compact and Light

Dimensions of 449 (W) x88 (H) x305 (D) mm (recording unit only, without projections) and a weight of approximately 10.5 kg for the recording unit and 7.5 kg for the measuring unit give the SIR-3000 a design with superior compactness and portability.
