The HFA3500TF, a low-profile, 3-phase, 3-wire, 3500W AC/DC enclosed power supply designed for industrial equipment including semiconductor fabrication, laser processing machines, and robots, rolled out by COSEL Co.
With a broad operating range of 180VAC to 528VAC, the HFA3500TF 3500W AC/DC enclosed power supply input voltage is suitable for a wide range of applications, including 3-Phase Delta or 3-Phase Star networks.
With a wide band gap (WBG) semiconductor and the most recent “energy optimized,” digitally controlled switching architecture, the 3500W AC/DC enclosed power supply can achieve an amazing 94% efficiency rating at 400VAC input and 65VDC output.
With the use of the trim function, the 48VDC and 65VDC output voltages of the HFA3500TF 3500W AC/DC enclosed power supply may be adjusted within a range of +15% to -50%.
With its cover on, the small, low-profile design is just 41 mm (1.61 inches) tall and has two variable-speed cooling fans. The HFA3500TF can produce up to 31.5kW when coupled in parallel with up to 10 units for greater power requirements.
The HFA3500TF 3500W AC/DC enclosed power supply low-profile form allows it to be integrated into compact machines more easily and saves important floor or rack space in industrial situations. It fits into the vertical space of a 1U (44.45 mm) rack unit, which is obviously useful in applications where space is at a premium.
In order to guarantee optimal performance and dependability within a compact design, the power supply has been engineered for maximum efficiency and tuned to eradicate hot spots and enhance cooling across its whole componentry.
In order to do this, the HFA3500TF 3500W AC/DC enclosed power supply combines the most recent advancements in power electronics with an inventive mechanical layout. Examples of these advancements include an optimized digitally controlled switching topology and a power stage that uses Silicon Carbide (SiC) MOSFETs and diodes, all of which work together to provide up to 94% efficiency at 400VAC input for the 65V output model.
Industrial equipment may be deployed anywhere in the world and supplied by 200V to 400V grids, meaning that a wide variety of input voltages is required for the power supply to function. System architects choose three-phase power solutions because they minimize single-phase peak loads and optimize load balancing on their networks. COSEL’s HFA3500TF is made to support three-phase three-wire star or three-phase three-wire delta installation.
The HFA3500TF 3500W AC/DC enclosed power supply has two separate output voltages that may be adjusted using the trimming function or the built-in potentiometer. Its input voltage range is 180 to 528VAC. Adjustable voltage ranges for the 48VDC/73A and 65VDC/54A models are 24.00 to 55.20VDC and 32.50 to 74.75VDC, respectively. The output power under nominal operating circumstances is 3.5 kW.
In addition to the main output, the HFA3500TF includes a 12VDC/1A auxiliary output which can be used for remote ON/OFF. The auxiliary output is isolated from the input, output, and Functional Ground.
Inrush current limiting circuitry, overcurrent and overvoltage protection, and thermal protection are all included in the HFA3500TF. The power supply demonstrate adaptability and durability since they can function in a temperature range of -10 to +70C. The unit is guaranteed to be ventilated by two cooling fans with automated speed control; nevertheless, a derating may be necessary based on the final equipment assembly style and climatic factors.
The HFA3500TF conforms with FCC Part15 class A, VCCI class A, CISPR11 class A, CISPR32 class A, EN55011-A, and EN55032-A regulations and has an input filter for system integration and conducted noise reduction.
The HFA3500TF features a 4,243VAC input to output isolation, a 2,829VAC input to ground (FG), and a 2,000VAC output to ground (FG). In accordance with IEC62368-1, the maximum leakage current at its rated load and with a 480VAC, 60Hz supply is 3mA.
Designed for integrated industrial applications in 1U height, the HFA3500TF measures 110 x 41 x 468mm [4.33 x 1.61 x 18.43 inches] (WxHxD) and weighs 3kg max.
The 48VDC output HFA3500TF-48 is appropriate for a variety of uses, including as machine tools, semiconductor manufacturing equipment, and measurement and analysis apparatus that must maintain sag immunity conditions as defined by the SEMI F47 standard.
Radio Frequency Power Amplifiers (RFPA) and chargers for 60V lithium-ion batteries work best with the 65VDC model HFA3500TF-65.
The HFA3500TF has the CE mark and UKCA and meets with safety regulations UL62368-1, EN62368-1, C-UL (corresponding to CAN/CSA-C22.2 No.62368-1), RoHS, and Low Voltage directives.
The HFA3500TF is intended for applications that allow fan-cooling; however, COSEL also offers the HCA3500TF, which is intended for baseplate conduction cooling, for certain industrial applications, such as welding robots, tooling machines, and electrolyzers, which are frequently required to operate in harsh environments without ventilation.
