Modular DC Power Supply 80V/18A/1440W
Chroma’s new 62000B series of Modular DC Power Supplies offer many unique features for Burn-in and plating/electrolysis applications. The features include a N+1 redundancy, high power densities, hot-swappable maintenance, remote ON/OFF and programmable control via the CAN bus.
Hot-Swap Operation
Equipped with the functionality of N+1 redundancy and hot-swap, the 62000B Series of modular DC Power Supplies are most applicable for 24 hours non-stop applications such as the SMD plating production lines, as well as product life burn-in test for IT products like DC converters, LCD backlight inverters and routers.
For continuous operation applications the modular hot-swap design allows engineers to replace the failure unit on-site without shutting down the entire system.
High Power Applications with CSU
The 62000B modular power supplies are capable of providing high power output up to 120KW/2000A with minimal specification degradation via CSU (Control & Supervisor Unit). Each chassis is designed to accommodate a maximum of 9KW and include current sharing capability to ensure system stability. In addition, for convenient control of even large power systems, a CSU is provided to set and display output and protection circuits via a standard CAN bus communication protocol.
A620007 CSU Key Features:
- Stand-alone controller for paralleled 62000B DC power for bulk power
- Digital encoder knobs and function keys
- Simultaneous display of output voltage and current
- Standard Analog programmable interface
- Standard CAN Bus
- Optional Ethernet interface
- User define I/O interface
CAN Bus’s Advantages
Controller Area Network (CAN) is a multicast shared, differential serial bus standard. CAN was specifically designed to be robust in electromagnetically noisy environments and can utilize a differential balanced line like RS-485. Introduced by Bosch in 1986 for in-vehicle networks in cars, it is used in myriad applications including factory automation, building automation, aircraft and aerospace as well as in cars, trucks and buses. CAN bus replaced bulky wiring harnesses with a two-wire differential cable. CAN provides services at layers 1 and 2 of the OSI model and uses a broadcast method for placing frames on the wire. CAN provides low-speed, fault-tolerant transmission of 125 Kbps up to 40 meters, which can function over one wire if a short occurs. Transmission without fault tolerance is provided up to 1 Mbps and 40 meters, and distances up to 1 km are achieved with bit rates of 50 Kbps. Bit rates up to 1 Mbit/s are possible at network lengths below 40m. Decreasing the bit rate allows longer network distances (e.g. 125 kbit/s at 500 m).
