CM150_SA

Introduction

CM150_SA is designed for positive current measurement, with automatic current range switching, with
measurement ranges from 1mA to 200A(150A max).

Features

• Current ranges 1mA, 10mA, 100mA, 1A, 10A, 100A(50Amax), 200A(150Amax)
• Unidirectional voltage and current measurement (in positive directions)
• Automatic or manual current range selection
• Over-current, sense buffer overload and over-temperature protection
• Current range switching time 100us
• Programmable range switching filters (time before range up/down switching) for load peaks suppression
• DUT Voltages up to 70V
• PLC control interface for Stand Alone mode without Ethernet control
• Ethernet control interface Modbus-TCP
• 0..10V analog outputs or internal sampling ADCs
• Voltage and current sampling up to 100ksampl/s
• PC delay sapling buffer for 2.5sec@100ksampl/s
• Analog outputs calibration and digital calibration for sampled data
• Configurable registers settings in EEPROM for stand alone using(use without Ethernet)
• DHCP or Static-IP configuration and unique NetBIOS name(Host name)
• Possibility of ADC calibration constants dedicated for every range extra.(If sampling over Ethernet is used.)
• Logarithmic analog output 0..10V indicator for measured current(indicate values 200nA .. 150A)
• Desktop use or on Top Hat Rail system holder (for EN 50022 – 35mm)

 

Measurement

Voltage

Output voltage is represented by voltage 0V – 10V on AO_V_value output pin or value sampled over Ethernet.
The voltage range is 70V (Or 50V selected with the jumper on main board).

Voltage range	Accuracy FSR	ADC LSB	AO_V_value voltage
50V	0,1%	10mV	0V..+10V
70V	0,1%	14mV	0V..+10V

 

Current

The current is represented by voltage 0V – 10V on AO_I_value output pin(according to the current range) or value sampled over Ethernet with selected range.

Current range	Accuracy	ADC LSB	AO_I_value voltage
1mA	0,2%	200nA	0V..+10V
10mA	0,2%	2uA	0V..+10V
100mA	0,2%	20uA	0V..+10V
1A	0,1%	200uA	0V..+10V
10A	0,2%	2mA	0V..+10V
100A (50A limited)	0,2%	20mA	0V..+10V(+5V)
200A (150A limited)	0,6% / 1,0%	40mA	0V..+10V (+7,5V)

Current range analog indication

The current range is represented by voltage 0V – 10V on AO_I_range output pin.

Current logarithmic analog indication

The current value + range is represented by voltage 0V – 10V on DAC_B output pin.
