HGLRC Specter 12S Power Distribution Board for 90A ESCs

The HGLRC Specter 12S PDB is a high-voltage power distribution board made to pair with HGLRC Specter 90A single ESCs on heavy-lift, X-class and cinelifter builds. It takes up to 12S, feeds as many as eight ESCs for quad, X8 or octo layouts, and carries the current sensor and BECs a large build's flight controller needs.

Key features

• High-current rails: rated 4 × 100 A continuous, 120 A peak.
• Up to eight ESCs with telemetry feedback, when the ESCs support telemetry.
• Built-in current sensor for real-time consumption and battery monitoring.
• Onboard BECs with 5 V and 12 V outputs for the flight controller, receiver and video gear.
• 30.5×30.5 mm M3 mounting fits standard stack holes on H- and X-frames.
• Capacitor supplied to absorb voltage spikes on the main input.

Specifications

• Input: up to 12S LiPo (44.4 V nominal, 50.4 V full)
• Continuous current: 4 × 100 A
• Peak current: 120 A
• ESC outputs: up to 8, with telemetry
• BEC outputs: 5 V and 12 V
• Mounting: 30.5×30.5 mm, M3
• Dimensions: 50 × 50 × 9.8 mm
• Weight: approx. 24 g

A full 12S pack sits at 50.4 V, so use wiring and any extra capacitors rated well above that, and set your flight controller's current-sensor scale before trusting its mAh readings.
