All NAI products are 100% designed and manufactured in the United States.

Module SDx
  • No. of Channels: 4 Channels
  • Frequency Range: SD1/SD5: 47 Hz - 1 kHz, SD2: 1 kHz-5 kHz, SD3: 5 kHz-10 kHz, SD4: 10 kHz-20 kHz
  • Resolution: 24-bit
  • Accuracy (±): ±1 arc-minute for single-speed inputs; ±1 arc-minute divided by the gear ratio for two-speed inputs
  • Interface:

Module DSx
  • No. of Channels: Multi-Channel
  • Frequency Range: Model dependent
  • Resolution: 16-bits (.0055°)
  • Accuracy (±): ±1 arc-minute (.017°) for 2, 3-channel; ±3.5 arc-minutes for single-channel (no load to full load)
  • Power (max.): 5 VDC at 570 mA; ±12 VDC at 160 mA (no-load) per channel. (Add 2.9 watts of ±12 VDC for every VA of output per channel). Therefore, a 1.5 VA Load adds ±12 V 181 mA average, or 288 mA peak per channel. External ±12 V input power can be utilized.
