Explore our specialized portfolio of military-grade isolation transformers, GaN high-power RF modules, and counter-UAV defense systems engineered for seamless integration into European aerospace, naval, and industrial control frameworks.
Berlin has rapidly transformed into one of Central Europe's most vital hubs for advanced manufacturing, defense technology research, and medical engineering. From the high-tech industrial park at Berlin-Adlershof to the expanded automation facilities in Siemensstadt 2.0, the requirement for robust power conditioning has reached an unprecedented peak. Modern electronic systems operating in these environments face severe electrical stress, high-frequency electromagnetic interference (EMI), line voltage spikes, and ground-loop noise.
As a veteran-owned small business with roots dating back to 1987 (CAGE Code: 0P327), AJ's Power Source Inc. (AJPS) delivers advanced OEM/ODM Isolation Transformer solutions designed specifically to resolve complex electrical isolation challenges. Unlike standardized off-the-shelf transformers, our custom magnetics integrate low-loss nanocrystalline or amorphous cores, multi-layer electrostatic Faraday shielding, and high-dielectric breakdown insulation tailored to DIN EN 61558-2-4, VDE, and international defense standards including MIL-STD-461 and MIL-STD-1399 Section 300.
System integrators and procurement directors searching for "Isolation Transformer Manufacturers in Berlin" are rarely looking for basic 1:1 transformers. Search intent analysis reveals four primary engineering priorities:
True galvanic isolation physically decouples the primary input circuit from the secondary output load, preventing DC current flow and breaking ground loops. In high-power industrial and defense applications, parasitic capacitive coupling across transformer windings acts as a low-impedance path for high-frequency common-mode noise ($I_{cm} = C_{p} \cdot \frac{dv}{dt}$).
AJPS engineers solve this through advanced triple-shielded Faraday topologies. By placing grounded copper shielding foils between winding layers, noise currents are diverted safely to the system earth ground rather than coupling into sensitive secondary avionics or sensor equipment. This achieves attenuation levels exceeding 120 dB from 10 kHz to 100 MHz.
Compare the technical parameters of commodity off-the-shelf isolation units with AJPS custom-engineered military and industrial magnetic solutions.
| Performance Parameter | Standard Commercial Transformer | AJPS Custom OEM/ODM Isolation Unit | Impact on System Reliability |
|---|---|---|---|
| Primary-Secondary Isolation Voltage | 1.5 kVAC to 2.5 kVAC | 4.0 kVAC to 10.0 kVAC Peak | Prevents catastrophic dielectric breakdown during high-voltage surge transients. |
| Interwinding Capacitance ($C_p$) | 150 pF – 500 pF | < 10 pF (Ultra-Low Leakage) | Blocks high $\frac{dv}{dt}$ switching noise generated by GaN/SiC power converters. |
| Common Mode Noise Rejection (CMRR) | 40 dB to 60 dB | > 120 dB (Triple Faraday Shielding) | Eliminates ground loop ripple in high-precision laboratory and radar equipment. |
| Thermal Insulation Class | Class B (130°C) / Class F (155°C) | Class H (180°C) / Class N (200°C) VPI | Prevents thermal runaway and insulation degradation under continuous full-load operation. |
| Ingress Protection & Sealing | Open Frame / IP20 Sheet Metal | IP65 / IP67 Fully Potted & Sealed | Survives immersion, humidity, salt fog, and abrasive dust in field installations. |
| Shock & Vibration Compliance | Standard Commercial (IEC 60068) | MIL-STD-810G & MIL-S-901D Grade A | Hardened against high-impact naval hammer shock and continuous tactical vehicle vibration. |

Direct answers to standard technical, regulatory, and logistics queries regarding OEM/ODM isolation transformers and export to Berlin.
Our custom isolation transformers are engineered to satisfy European industrial and safety directives, including DIN EN 61558-2-4 (Safety of Transformers), IEC 60601-1 (Medical Electrical Equipment where applicable), and Low Voltage Directive (LVD) 2014/35/EU. For defense programs, we qualify units against MIL-STD-810G (Environmental), MIL-STD-461 (EMC/EMI), MIL-STD-1399 Section 300 (Naval Power Quality), and MIL-S-901D Shock requirements.
Our engineering workflow begins with a detailed requirement capture detailing input voltage range, secondary tap outputs, frequency (50Hz, 60Hz, 400Hz, or high-frequency switching up to 500kHz), thermal dissipation limits, and physical mounting envelopes. We then issue 3D CAD models, electrical schematics, and thermal simulation reports for design sign-off prior to prototype fabrication.
Yes. In over 70% of customer programs, starting from one of our proven catalog transformer or power converter platforms reduces Non-Recurring Engineering (NRE) costs by up to 60% and cuts qualification timelines significantly. Modifications can include custom connector interfaces, specialized mounting brackets, specific secondary winding ratios, and custom conformal coatings.
We offer single, double, and triple electrostatic Faraday shielding using high-purity copper foil wrapped between winding layers. This construction effectively shunts common-mode noise currents to ground, delivering a Common Mode Rejection Ratio (CMRR) exceeding 120 dB and reducing parasitic capacitance to under 10 pF.
