Product Overview
The 21.5" rack mount monitor AP-21OPLR/21.5" is part of the Industrial Rack Mount LCD Monitor family. Recommended for sCADA overview racks, server room KVM drawers and network operations center consoles. Typical scenario: 1920×1080 widescreen content at 250 NITS across a 476.64×268.11 mm active area; 0 ~ 50 °C operation.
