What are the power requirements for an HID iCLASS reader with a SABRE Module?

1. Normal Operation

  • The HID iCLASS reader with the SABRE module requires less than 200mA during peak load operations.
  • Sustained current is less than 100mA.

  • The SABRE module adds approximately 20mA when Wi-Fi is enabled.

2. Firmware Update – SABRE Module

  • During a firmware update, the SABRE module uses less than 20mA.

3. Firmware Update – HID iCLASS Reader

  • While not related to Safetrust technology, an HID reader firmware update using an HID firmware update cardcan require up to 450mA.

  • Important: If your panel cannot supply 450mA, the update may brick your HID reader. This is a known issue with HID iCLASS readers.

Recommendations

  • Do not perform field firmware updates on HID readers unless you have a spare reader on hand.

  • The update process takes 15-20 minutes per reader and has a high probability of failure based on experience.
