ODA Technologies EX50-72

Product Overview: The ODA Technologies EX50-72 programmable single-axis DC power supply is a premium industrial-grade high-efficiency switching instrument belonging to the world-renowned EX Series portfolio, engineered, manufactured, and laboratory-certified 100 percent in South Korea by ODA Technologies (Korea Origin). Within high-tier electronic engineering research and development (R&D) facilities, hyper-scale automated testing equipment (ATE) frames, electric vehicle (EV) battery pack assembly grids, and semiconductor aging loops, utilizing a heavy-duty continuous DC voltage source that delivers micro-millivolt accuracy matched with extensive remote software control is a critical operating standard.

The EX50-72 configuration answers these complex production parameters directly, deploying an advanced switching topology that channels a massive power envelope spanning from 3.6 kW to 4.0 kW, completely outperforming standard low-capacity bench power units like Korad, Rigol, or Siglent common to retail markets.

Flexible CV / CC Operational Loops and Automated SCPI Command Control: The internal mechatronic backbone of the EX50-72 build iteration provides concurrent support for two fundamental localized feedback processing circuits:

Constant Voltage (CV) Mode: The internal calculation processor locks the electrical output voltage firmly to the programmed reference value (fully adjustable across a 0 to 50 VDC span), allowing output current to modulate based on active load demands.
Constant Current (CC) Mode: The sensor loop clamps the output current vector strictly to the selected user threshold (fully adjustable across an extensive 0 to 72 A envelope), automatically adjusting target output voltage limits to safeguard connected circuits.

This automated CV/CC loop transition makes the instrument an exceptional asset for rigorous charge/discharge testing of raw Lithium cells, automotive EV battery packs, or high-thrust industrial DC motor start-up characterization scripts. Furthermore, the unit supports decentralized remote interface routing via built-in physical connection blocks including RS232, RS485, and USB ports, alongside an optional field-upgradable TCP/IP Ethernet network module. Complying fully with global standard SCPI (Standard Commands for Programmable Instruments) criteria, automation technicians can seamlessly compose remote execution code block routines or build automatic data-logging scripts straight via standard industrial software platforms including LabVIEW, C#, Python, or centralized PLC industrial controllers.

High-Fidelity Resolution Matrix and Advanced Wave Ripple Suppression: The power transmitter delivers superior control resolution and extreme data stability, minimizing tracking errors caused by grid thermal shifts or dynamic line noise variables:

Programming Accuracy Window (Voltage): Plus or minus (0.1 percent plus 75 mV)
Programming Accuracy Window (Current): Plus or minus (0.1 percent plus 216 mA)
Readback Verification Accuracy (Voltage): Tracks tightly within plus or minus (0.1 percent plus 50 mV)
Readback Verification Accuracy (Current): Tracks tightly within plus or minus (0.1 percent plus 144 mA)

Engineered with specialized high-frequency switching filtering sheets, the output channel suppresses residual wave gợn sóng and electrical hash down to an ultra-clean threshold of less than or equal to 15 mVrms running along a dải bandwidth from 20 Hz up to 20 MHz. Both Load Regulation and Line Regulation metrics lock securely at less than or equal to 50 mV, validating that the electrical power delivery remains entirely smooth and shielding highly sensitive automated computing components from premature voltage stress breakdown.

🛠️ FIELD SCALING INFRASTRUCTURE & MECHANICAL ENGAGEMENT RULES:

Standardized 19-Inch 2U Rackmount Enclosure: The mechanical housing profiles a highly optimized physical block showing a width of 426 mm, a height of 88 mm, and a total depth of 550 mm, with a net mass of 13.6 kg. This compact outline enables structural integration straight into standard industrial 19-inch electrical equipment racks, utilizing exactly 2U of vertical panel slot space and optimizing floor layout efficiency.
Scalable Master-Slave Architecture Beyond 10kW: For heavy-duty process arrays demanding power boundaries exceeding standard constraints, the EX Series allows automation crews to configure multiple units in series links (to boost absolute voltage spans) or parallel arrays (to scale up loop current limits). This setup drives system output capacity past 10 kW while maintaining unified remote orchestration via the principal SCPI bus network link.

Hardened Transient Safety Protection and Onboard Configuration Memory: To safeguard the valuable external phôi components under active calibration, the ODA EX50-72 circuitry is reinforced with premium heavy-duty protection mechanisms: native OVP (Over Voltage Protection) tracking inside a plus or minus (1 percent plus 0.5V) boundary, and OCP (Over Current Protection) locking inside a plus or minus (1 percent plus 7.2A) envelope. If an external circuit short or thermal surge strikes the tracking loop, the safety barrier triggers an automated shutdown response in less than 80 ms, isolating connected loads before electrical damage can migrate.

The front interface links directly with an internal solid-state memory array capable of caching up to 10 independent test profile parameter configurations (storing designated voltage targets, maximum current limits, and custom safety threshold boundaries concurrently). This capability streamlines automated plant changeovers during model shifts without forcing manual device re-configuration. The master system runs flawlessly across a standard global industrial utility input range of 220 VAC plus or minus 10 percent, handling grid wave frequencies of 50 or 60 Hz with a maximum continuous electrical load draw parameters rated at 4.6 kW.
