Function Feature

HP18 series digital display voltmeter and ammeter are mainly used to real-time measure the AC voltage, AC current, DC voltage, DC current in the electric circuit. It can be added with 1-channel out-of-limit alarm contact output function according to the actual demand. It has the following featlurec：
★Measurement adopts the AC sampling RMS formula mode. Waveform and frequency change will not influence the accuracy of measuring basically.
★The display multiplying power can be set freely. It can easily match any specification of PT, CT or shunt.
★Buckle mounting way, no need of any tools to fulfill the installation.
★It provides the measuring error correction function, which avoid any deviation of measured value due to environmental change, time variation or other factors.
★It has polarity indication function, which can measure the reverse DC signal(only for DC meter).
★The upper and lower limit of out-of-limit alarm can be set freely. The upper and lower limit alarm can use the same relay to output.
★It has the setting functions such as alarming differential gap, alarm electricity suppression, alarming lock, delay time of generating alarm and releasing alarm, and so on.
★It can be customized in this way, to input standard analog signal(for example, DC4~20mA or 0~10V, and so on), then display the electric parameters or non-electricparameters such as Mpa,C, rpm,r/min,m/min, ★and so on. Or it can be customized to the special meter which display data can be set freely.

Model & Specification & Selection Table

Basic Parameter

★Measuring range: 
AC ammeter: AC 0.05~6A, when it is more than 6A, it needs to connect a */5A or*/1ACT externally and set the display multiply power 
DC ammeter: DC0.05~6A, when it is more than 6A, it needs to connect a */75mV shunt externally and set the display multiply power 
AC voltmeter: AC 10~600V, when it is more than 600V, it needs to connect a */100V PT externally and set the display multiply power 
DC voltmeter: DC 0.1~600V
★Accuracy class:±(0.5% range +1 character)
★AC signal input frequency range:40~70Hz 
★Power consumption of input loop:<0.5VA 
★Measure and display mode: RMS measuring, four-digit LED valid value display 
★Resolving ability: the bottom number 1 character 
★Measuring rate: about 3 times/s 
★Polarity indication: it can display-, used to measure the reverse DC signal 
★Overflow indication: the upper limit overflow displays "--", the lower limit overflow displays"--"
★Auxiliary power supply: AC 220V±10%, AC/DC 80~260V(other specifications can be customized)
★Power consumption of auxiliary power supply:<3VA 
★Alarm contact output: the upper and lower limit of alarm adopts the same relay to output, and then use LED lamp to indicate their alarming status 
★Alarm contact capacity: AC 250V/1A 
★Alarming upper and lower limit range: can be set freely within the measuring range 
★Working environment: temperature is-10～+50C, humidity <85% RH, without any corrosive gas 
★Safety withstand voltage: using the AC 2kV withstand voltage test to measure betweenthe input terminal and the power supply terminal, between the input terminal and the alarm contact terminal

Order Notice

When order, please clarify the model, specification(including the measurement input specification and power supply), and quantity, if the user needs any special requirements, please mark!
For example 1: model HP1841-5X1 AC75/5A power supply AC220V quantity 200pcs, which means the 96 x48 AC ampere meter, and it's defaulted as 75/5A when out-of-factory.
For example 2: model HP185U-9X1 input DCO-10V and display O-50Hz power supply AC220V quantity 300pcs, which means the 96x96 DC voltmeter, and the panel display unit is Hz.
For example 3: model HP185U-7X1 DC100V power supply AC/DC 80-260V quantity 100pcs.
