Tense DJ-A96T Three Phase Digital Ammeter
The Tense DJ-A96T is a square, panel mounted digital AC ammeter engineered to continuously measure and simultaneously display the current values across three phase electrical loads. Housed in a standardized 96x96mm outer bezel footprint, the device features a prominent 3×4 digit red LED display matrix. This design allows maintenance engineers, plant operators, and switchgear assemblers to assess the electrical balance of all three lines (L1, L2, L3) simultaneously without cycling between screens.
Key Features
-
Simultaneous 3 Phase Multi Display: Outfitted with three independent, stacked rows of 4 digit red LED screens (14 mm digit height), providing continuous monitoring of currents across all phases.
-
Wide Current Transformer Scaling: Fully programmable via the front keypad to scale current transformer (CT) transformation ratios from standard 5/5A up to high capacity industrial 5000/5A networks.
-
Dual Measurement Range Capabilities: Capable of directly reading localized minor line current loads from 100 mA up to 5.5A AC without requiring an external current loop transformer.
-
Intuitive Tactile Interface: Equipped with user friendly membrane buttons (
SET,UP,DOWN) located on the front faceplate for quick parameter configuration, CT scaling adjustments, and menu navigation. -
Robust Panel Front Mount Architecture: Built into a sturdy plastic housing that mounts securely into standard 91X91 mm square structural cutouts using side integrated clamping rails.
