Example 1: If the customer requires a DC ammeter, the product name is ammeter, the input method is DC, the external dimensions are 48 × 96, and the variety is specified
Construct a programmable display instrument, with a display mode of a row of digital tubes, and the corresponding order code for a range of DC100A/75mV
For: PA606C-48P1 DC100A/75mV.

■The product mainly consists of sampling circuit, power circuit, display circuit, and functional module circuit.
■Design multiple meters for users to choose from based on the measurement parameters of the power grid, including single-phase AC voltage, AC current, DC voltage, and DC current
Frequency meter, three-phase AC voltage, AC current meter, etc.
■Using long-life LED to display battery information, the reading is intuitive; Wide range of 1% to 100% for accurate measurement, good linearity
Strong overload capacity, high accuracy, stable and reliable operation.
■Small in size, lightweight, and designed with modular structure, it can directly replace analog indicator instruments and related auxiliary components.
■The voltage, current, and weak current wiring terminals are separated by fence and plug-in, making the wiring operation simple and requiring minimal on-site construction.
■Multiple expansion function modules are available for users to choose from: switch output can achieve overload opening and closing, undervoltage, undercurrent protection, etc;
RS485 communication enables networked meter reading and networking with different PLC and industrial control computer communication software in the industry, enabling measurement and control
System.
■The dashboard has four programming buttons, allowing users to easily program and set instrument parameters on site, with strong flexibility;
The button adopts a PET material layered bridge structure design, with two colors injected in two colors. At the same time, in order to avoid electrostatic breakdown problems, a device is installed below the button
Convex concave structure, with good mechanical properties, bending resistance, wide temperature range, good mechanical properties, anti-static, gas resistant, waterproof, and anti-corrosion
Dusty, non-toxic, odorless, with a good touch feel, easy and convenient to operate; The key character mold is formed, and the character gloss does not fade or peel off.
■The instrument measurement display can be freely matched by the user according to the transformer ratio, and real-time display of the primary side electrical parameters.
■The panel adopts a transparent PMMA material frameless large screen design, with a pure flat appearance and excellent viewing angle effect. The material has high hardness and good light transmission
Surface gloss, good weather resistance, and scratch resistance.
■The product design fully considers production technology and green environmental protection. The shell is made of flame-retardant materials, which are resistant to vibration, corrosion, and beautiful
Safe and reliable, all indicators meet national standards.
