SELECTION LOGIC
Choose the Z Series for Low-Height Installation
The Z Series should answer low-profile packaging and lower-power off-highway searches before repeating generic PTC-heater features.
90 mm
Low Package Height
Evaluate the flat enclosure where vertical clearance is restricted.
2–12 kW Rated Power
Lower-Power Thermal Duty
ZA
Housing-Mounted Interfaces
Confirm both electrical connectors and their mating parts as part of the heater release.
APPLICATION EVALUATION
Prioritize Construction Machinery and Light-Duty Trucks
The Z-Series title artwork specifically names construction machinery and light-duty trucks. The supplied application artwork also shows electric buses, so bus use remains a project-specific engineering evaluation.
- Battery preheating or temperature conditioning
- Cabin and auxiliary liquid-heating circuits
- 2–12 kW heating-duty fit to confirm
- Off-highway or commercial-vehicle voltage window
- Available 243 × 165 × 90 mm package space
- Vibration, dust, coolant and validation scope
MECHANICAL PACKAGE
Validate the 90 mm-High Heater Envelope
The low-profile enclosure can solve vertical-clearance constraints while the two same-side coolant connections and electrical interfaces still require service space.
- 243 × 165 × 90 mm published reference
- Two Ø20 mm coolant ports on the interface side
- Mounting ears, fasteners and installation orientation
- Hose engagement, bend radius and drainage
- Connector mating and service clearance
- Released tolerances, vibration and mounting loads
INTERFACE RELEASE
Confirm Both ZA Electrical Interfaces
The source-folder label associates this ZA configuration with high- and low-voltage Amphenol connectors, and the orange housing carries visible Amphenol marking. Exact series, part numbers, keying and mating definitions are not published.
- Orange connector function, series and mating part
- Circular connector function, series and mating part
- Keying, HVIL, pinout, current rating and grounding
- Connector sealing and service access
- Ø20 mm hose specification and clamping
- Configuration-specific drawing and bill of materials

The supplied Z-series parameter table lists a weight of 3.45 kg. Confirm the installation mass, electrical interfaces and released drawing for the selected configuration. Certification and test evidence must identify the applicable product and revision.
PRODUCT VIEWS
Inspect the Housing, Mounts, Ports and Connectors
Use supplied views for early screening and the released drawing for production packaging.
CONTROL & PROTECTION
Convert Listed Functions into a Machine Test Matrix
CAN, PID and protection names support screening; release needs thresholds, reactions, feedback, recovery and revision traceability.
01
Command
CAN requests, enable logic, wake-up, shutdown and restart behavior.
02
Regulation
PID ownership, power demand, measured values and automatic limiting.
03
Protection
Voltage, current, short-circuit and overtemperature trigger conditions.
04
Evidence
Fault injection, derating, recovery, diagnostics and controlled software revision.
QUALIFICATION EVIDENCE
Request Records for the Exact Z-Series Configuration
Factory and certificate-display artwork can support supplier review, but product approval should rely on controlled records matching the exact heater, connectors, software and validation scope.
- Released product specification and 2D / 3D drawing
- ZA connector and mating-component definitions
- CAN document and software revision
- Electrical, EMC, ingress and environmental reports
- Prototype inspection and project validation records
- Approved warranty and commercial terms
FAQ
Z-Series Low-Profile Coolant-Heater Questions
Answers separate supplied facts from details requiring a controlled project release.
The Z Series technical specification lists a rated power range of 2–12 kW. Confirm the final electrical configuration and required output for your project.
The supplied technical panel lists 200–800 V and describes rated voltage as customizable. Confirm nominal voltage, minimum and maximum DC voltage and transient requirements for the exact Z-Series configuration.
The product-display artwork lists 243 × 165 × 90 mm and marks Ø20 mm coolant ports. Use those figures as an early package reference and request the released drawing for tolerances, mounting and hose engagement.
The source-folder label associates this ZA configuration with high- and low-voltage Amphenol connectors, and the orange housing is visibly marked in the supplied product imagery. The exact series, part numbers, keying, pinout and mating components are not published and must be confirmed.
The supplied technical panel lists CAN bus with enable control, PID control, fault self-diagnosis, automatic power limiting, and overvoltage, undervoltage, overcurrent, short-circuit and overtemperature protection. Thresholds and response behavior require project documentation.
The supplied artwork shows construction machinery, electric trucks and electric buses. The Z-Series title artwork specifically prioritizes construction machinery and light-duty trucks; suitability depends on heat duty, voltage, coolant circuit, packaging, vibration, contamination and validation requirements.
