Power Module Model A673905

Chroma A673905 Power ModuleSpecifications are preliminary and subject to change without notice.

Automotive power supply systems operate in complex environments and under harsh conditions that can lead to component or system failures. The A673905 power module simulates various power fluctuations between sources and loads—including cold crank, load dump, load/unload, and gradual rise/fall margin testing—helping to identify potential product issues before they occur.

Designed for 12V, 24V, and 48V automotive power systems, the A673905 provides precise voltage regulation in Normal Mode while also offering a Combination Mode for margin testing. This allows for accurate simulation of automotive power changes in various real-world conditions.

  • Normal Mode: Provides 3-55V with 1mV resolution
  • Combination Mode: Cold crank, load dump, load/unload, and gradual rise/fall margin testing

Automotive electrical systems are required to undergo minimum power consumption tests in "sleep mode" to control battery drain when the vehicle is stationary. The A673905 power module is designed with high-precision, microampere-level (µA) current measurement capabilities, allowing for highly accurate measurement of the device under test's power consumption.

'Slew rate' refers to the rate of change of the output voltage over time when the power supply experiences load or input changes. This reflects the power supply's ability to respond to sudden load demands or changes to its input. The A673905 power module offers programmable slew rate functionality, allowing linear adjustments from 0.001 to 1 V/ms to simulate real-world usage scenarios. This enables verification of product stability and response under rapid input voltage changes or during startup transients (e.g., cold crank).


The module provides over-voltage protection (OVP) and over-current protection (OCP) for the voltage battery (VB). Users can customize the protection limits, and if the device under test exceeds these during operation, the protection mechanism activates immediately to prevent damage. To prevent false triggering of this mechanism due to inrush current during power-on, the module offers a Protection Delay Time feature to ensure uninterrupted testing.

The A673905 includes under-voltage protection (UVP) and under-current protection (UCP) for the VB, which can effectively monitor whether the voltage and current of the device under test are lower than the set value in real-time, from start to finish. This helps detect components that do not meet operating conditions or circuits operating below normal lower limits.
