Personal Safety Voltage Detector ( 220V~35KV ) ( HTC-PSD II )

Description

The HTC PSD‑II Personal Safety Voltage Detector redefines portable AC voltage detection for electrical professionals, utility workers, site inspectors, and technicians operating in high-voltage environments. This pen‑style personal alarm unit delivers reliable, contactless voltage warning for systems ranging from low‑voltage distribution to ultra‑high transmission lines. Compact and wearable, it serves as a continuous safety sentinel during inspections, maintenance, and job‑site movement.

This device is engineered to detect AC voltages from 220 V through 35 kV, with warning distances that scale from 0.1 to 0.4 m at 220–380 V, up to 0.7–1.2 m at 10 kV, and 1–2 m at 35 kV—providing advanced notice of proximity to live conductors, even without direct contact. Its sensitivity covers standard AC line voltages to high-voltage overhead lines and distribution equipment, offering unmatched awareness across electrical environments.

Designed for rugged field use, the PSD‑II features a clear visual indicator and audible alarm, allowing quick interpretation of live voltage detection. A built‑in self‑test function ensures ongoing readiness and reliability throughout the workday. Additionally, it offers low power consumption, providing approximately 50 hours of continuous use from two AAA batteries before needing replacement.

Measuring approximately 52 × 60 × 21 mm and weighing just 0.3 kg, the PSD‑II is light enough to clip onto protective headgear, tool belts, or safety jackets—allowing professionals to work hands‑free while constantly staying alert to voltage dangers.

A bold 75 dB alarm at one meter ensures that voltage detection cannot be missed—even in noisy industrial or outdoor environments. Meanwhile, the device meets stringent safety and electromagnetic standards, including EN 61326‑1 compliance, giving users confidence that the PSD‑II is both safe and dependable.
