Engineered systems are custom power supply systems and integrations created when standard catalog products don’t fully meet your technical or operational requirements—often delivered as turnkey racks or subsystems for automated test and specialized applications.

Choose an engineered system when you need custom integration, modified performance, specialized controls, multi-source sequencing, or turnkey rack delivery—especially in aerospace/defense test, semiconductor process power, and OEM integration scenarios.

AMETEK’s Solutions team delivers systems ranging from OEM integrations to modular avionics ATE power subsystems, turnkey solar array simulators for satellites, and customized systems such as PV emulation, radar bus simulation, and DC source + regenerative load solutions.

Yes. The Engineered Systems offering includes catalog product modifications to meet specific application requirements (electrical behavior, integration constraints, system packaging, etc.).

It means delivering a configured power subsystem (hardware + controls + protection + interfaces) that fits your ATE workflow, reduces bench complexity, and speeds system commissioning—often as a ready-to-integrate rack or platform.

A solar array simulator is used to emulate photovoltaic I‑V behavior for validating spacecraft power electronics such as PCDUs and MPPT algorithms, enabling repeatable testing without a real array.

Because spacecraft power systems must handle changing conditions (operational dynamics, bus regulation behavior, and control algorithms). A simulator provides controlled, repeatable I‑V emulation to verify system performance before deployment.

A battery string simulator is a test system that replicates battery pack behavior to support spacecraft and system validation—helping teams test charging, discharge behavior, and system interactions without using real flight batteries.

Battery string simulators commonly support:

• Static mode: outputs a terminal voltage corresponding to a selected state-of-charge
• Dynamic mode: updates terminal voltage by tracking charge/discharge energy over time for more realistic behavior

Radar power bus simulation provides sequenced programmable power to test facilities so engineers can validate how radar subsystems behave across operating conditions without relying on final power infrastructure.

A spacecraft power bus simulator provides controlled power stimulus to spacecraft subsystems—often modeling multiple independent sources—so payload and subsystem interfaces can be verified before flight integration.

PV emulation reproduces solar-array electrical behavior so teams can verify inverter controls (like operating-point tracking) and system response under repeatable lab conditions.

Thermal vacuum heater power supports TVAC satellite chamber testing, enabling controlled heating during vacuum-based qualification and environmental testing.

It’s a system combining programmable DC power delivery with an energy absorption or regenerative load capability, supporting development and test workflows where power must be sourced and then safely absorbed/managed.

Engineered systems often support lab and ATE integration through standard command/control approaches. For example, AMETEK’s solar array simulator systems emphasize remote control and integration-friendly operation for advanced test workflows.

Provide your required voltage/current/power range, number of channels, transient behavior, control interfaces, safety needs, rack constraints, and the DUT/test standard requirements. (We’ll map this to an engineered integration approach.)

AMETEK positions engineered solutions for medical and semiconductor OEM integrations, avionics/military test stands, space power validation, and other advanced test applications.

Yes—engineered solutions include turnkey solar array simulators for satellites and spacecraft test equipment options listed under the Engineered Systems portfolio.

PV simulators create a controlled light source that mimics sunlight, allowing researchers to test the performance of solar cells and modules in a lab setting, regardless of weather conditions.

Simulators can be categorized by their light source, such as Xenon arc lamps for continuous light or pulsed laser-based systems. They can also be classified by their spectral match to sunlight, with AAA-grade simulators providing the highest spectral accuracy.

Simulators are used to test solar cell efficiency, determine IV curves, and evaluate the performance of different module designs under varying conditions.

PV simulators provide controlled and reproducible testing conditions, allowing for accurate comparison of different solar cell technologies and module designs.

Consider the specific requirements of your testing, such as the size of the area to be illuminated, the desired spectral match to sunlight, and the available budget.

A Spacecraft Power Bus Simulator is a system that models the electrical power distribution network of a spacecraft, allowing engineers to test and verify designs before hardware implementation.

These simulators are crucial for verifying the functionality of spacecraft subsystems, their interfaces, and overall system performance.

Calibration is typically done using a reference solar cell or a photodiode to ensure the simulator's output is accurate and stable.

Simulators may not perfectly replicate all aspects of natural sunlight, such as the spectral distribution, and may have limitations in terms of irradiance range.

It simulates the harsh vacuum and temperature conditions of space. These systems are used to test spacecraft components to ensure they can handle thermal extremes and operate reliably in orbit.

Key considerations include:

• Thermal control precision
• Heating and cooling power
• Size and shape of the test article
• Integration with vacuum systems and sensors

A vacuum furnace removes air from its chamber to allow heat treatment of metals or components in a controlled atmosphere, avoiding oxidation and contamination.

Thermal evaporation is a method for applying thin material coatings. The source material is heated in a vacuum until it vaporizes, then condenses onto the target surface.
