Product Description:

The PSI63C0.620-L2is a powerful medium-frequency inverter that is designed to provide accurate current control for different type of welding systems including spot, projection and resistance seam welding. This inverter is particularly economical as it has a low cost of ownership and it significantly extends the operation time of welding electrode. This smart inverter is produced by Bosch Rexroth, and it useful for the welding of materials that are traditionally considered difficult. This includes welding high-strength metals, three-sheet stack-ups, and aluminum materials. The inverter offers extensive control functions and system integrations. Most components required by the product for operation are already installed into its housing unit, this reduces the overall cabling requirements of the product.

The PSI63C0.620-L2 inverter also regulates the thermal load and mechanical pressure of the electrode tips. The controlled and improved energy insertion feature of this product also increases the range of welding materials and its leakproof features. The product series of this inverter is renowned for their compact housing design, that makes their installation in areas with limited spacing possible. The supply voltage range for this product is measured to be between 500 volts to 690 volts. The required connection cross-section is 35 millimeter square and its maximum current ranges from 800 amperes in primary current to <<36,000 amperes in secondary current.

The switchgear cabinet loss of this unit at maximum power is 200 watts. The unit is able to function without derating at ambient temperatures as high as 55 degrees The ambient air needs to be free of metal vapors at high concentrations, corrosive agents, acids, and salts. These can also contribute to corrosion. The PSI63C0.620-L2is designated IP20 protective rating designed for modular enclosure. For proper function, moisture condensation should be prevented. The unit is rated Humidity Class F according to DIN 40040.

Frequently Asked Questions about PSI63C0.620-L2:

Q: Is the PSI63C0.620-L2 a water cooled device?

A: This frequency inverter is not water cooled. Instead, it features an air blower that is responsible for its temperature regulation via forced ventilation.

Q: Can the PSI63C0.620-L2 frequency converter be installed and used without a control cabinet?

A: No. The inverter is an IP20 product, it requires installation into a portable welding box system that can provide reliable protection according to at least the IP54 category.

Q: How can operators carry out the configuration of this product?

A: The PSI63C0.620-L2 can be configurated through a PC unit installed with the appropriate software. The connection of the motor with the configuration PC is done through the BOS 5000 operator interface.

Q: Why does the PSI63C0.620-L2 require less cabling compared to other inverter devices?

A: The minimal cabling required by the PSI63C0.620-L2 is due to its housing design that already have most of its operation components already integrated into its housing.

Q: How does the PSI63C0.620-L2 communicate error message?

A: There are LED diodes on the housing of the PSI63C0.620-L2. These Diodes communicate the operation status of the controller in real time.
