Maccor Options

Reference (Auxiliary) Voltage Inputs

Voltage Inputs, available in blocks of sixteen (16), are easily assigned to test channels. These voltage inputs are high impedance, fully isolated, and are offered in various ranges such as: ±5 volts, 0 – 10 volts, etc. Any combination and quantity of voltage inputs may be assigned to a test channel. Data measured by these inputs becomes part of the data record for the test channel assigned and voltages measured can control flow of the test procedure (schedule).

Reference voltage inputs may be used for: 3 or 4 reference electrode experiments; measuring individual cells within a pack, monitoring external voltages, etc. Readings may be viewed or plotted in real time, or plotted either as a single input or overlay all the inputs associated with the experiment.

Thermocouple Inputs

Thermocouple Inputs, available in panels with sixteen (16) inputs, are software assignable in any combination or quantity to a test channel. Thermocouple Input panels are offered for Type "K", "T", and "J" thermocouples. Each panel must be for one thermocouple type.

Data measured by these inputs becomes part of the data record for the test channel assigned creating a historical record of temperature for the test schedule. Temperature functions can be used to control flow of the test schedule on channels with thermocouple inputs on the basis of absolute temperature, T/dt, T, and several others.

Thermistor Inputs

Thermistor Inputs, available in panels with sixteen (16) inputs, are software assignable in any combination or quantity to a test channel.

Data measured by these inputs becomes part of the data record for the test channel assigned creating a historical record of temperature for the test schedule. Temperature functions can be used to control flow of the test schedule on channels with Thermistor inputs on the basis of absolute temperature, T/dt, T, and several others.

Pressure (Strain Gauge) Inputs

Pressure Inputs, available in panels with sixteen (16) inputs, are software assignable in any combination or quantity to a test channel.

Data measured by these inputs becomes part of the data record for the test channel assigned creating a historical record of pressure for the test schedule. Pressure functions can be used to control flow of the test schedule on channels with pressure inputs on the basis of absolute pressure, P/dt, P, and several others.

External Charge Controller

External Charge Controllers can be added to any or all of the test channels. These devices work as follows: The test channel retains all of the capabilities it normally has. In addition, tests run on the channel can connect to an external charger during a charge controller step. During such connection, all the data gathering capabilities and all the step end conditions of the test channel can still be used.

External Load Controller

External Load Controllers can be added to any or all of the test channels. These devices work as follows: The test channel retains all of the capabilities it normally has. In addition, tests run on the channel can connect to an external load during a load controller step. During such connection, all the data gathering capabilities and all the step end conditions of the test channel can still be used.

Frequency Response Analyser (EDA 0305)

Maccor's Frequency Response Analyser (EDA 0305) may be added to new and existing test systems running Maccor's Windows based software. The EDA and eight (8) position Multiplexer add full AC impedance analysis to a test system allowing frequency scans without disturbing the device under test or its connections at any time during the test. The positions on the multiplexer are assignable to any test channel in the system.

Data from the EDA include: frequency, magnitude, phase angle, real and imaginary impedances, and capacitance or inductance. Standard plots available in the MIMS Client include: Nyquist, Bode, magnitude, real, imaginary impedances, and phase angle versus frequency, real or imaginary impedances, cycle, voltage, capacity, energy, or power.

LED Status Indicators

New test system's interface can be fitted with a LED status indicator. The LED provides a visual indicator on the test system when the channel is active.

SMBus Battery Interface

The SMBus battery interface, offered in modules of twelve positions, is used to read and write to certain registers of SMBus compliant battery packs. The fields read by the test channel are added to the channel's data file. The test channel responds to different SMB alarms during testing. If a test step ends on an alarm, the data file will have the appropriate end code.

The data from the Smart Battery pack consists of header and data information. The data read from the SMBus Battery pack can be viewed in real time for the test channel the pack is assigned.

8-Bit Digital Inputs

This hardware option provides eight TTL optically isolated input bits for a tester channel. The flow of the test procedure may be controlled based on the bit values (high or low).

7-Bit Digital Outputs

With this hardware option, a tester channel may set individual lines of TTL outputs high or low during the test. These lines may be used to trigger an event or simply display status lights.

Telecom Pulsing

This option allows test channels to perform popular Telecom and similar pulse profiles. The period for the tester channel is adjustable from 4 to 10 mS, with pulses available from 100 µS on up. All channels on a single controller board are set to the desired period. In the test procedure, the magnitude and pulse duration are set.

Sub-Millisecond Pulsing

For demanding tests, this options provides the flexibility to create a train of up to sixteen sub-millisecond pulses. Individual pulses may each be less than 100 µS provided one of the pulses is greater than 1 mS. Once the train has been created, it is looped until the programmed end criteria is reached.

Uninterruptible Power Supply

Test systems are designed to detect power outages and avoid losing any data when a UPS is used on the logic power supplies and tester PC. System can be user configured to restart suspended test when power is restored or wait for user intervention depending on the length of the power outage.
