Re: your question "Is load shedding required for a backup system not designed for peak shedding?" If the emergency system power source has adequate capacity to carry safely all emergency loads that are expected to operate simultaneously, and it does not have emergency loads [Article 700], legally required standby loads [Article 701], and optional standby system loads [Article 702], then load shedding is not required. In summary, the generator must have the capacity for the emergency load and a separate transfer switch is required for emergency loads.

DIN Rail-Mount Drive and Line Reactors
TCI, Milwaukee, Wis., recently increased the versatility of its KDR™ optimized rrive reactors and KLR™ line reactors by introducing DIN rail drive reactors, a separate line of KDR optimized drive reactors and KLR line reactors equipped with a DIN rail mount. TCI is also introducing UL Listed KDR optimized drive reactors and KLR line reactors, as well as UL Type 1 and Type 3R enclosures for the UL Listed reactors. The devices are designed to be compatible with any 35mm DIN Rail and to mount to either "Standard Steel High Profile" or "Heavy Duty Steel" DIN Rails. Using DIN Rail drive reactors reduces installation time by over 75%. Installation requires no specialized tools. TCI reactors applied to the line side of a VFD drive will greatly improve the overall performance of the drive. The additional circuit inductance will reduce AC voltage waveform line notching, DC bus overvoltage trips, inverter overvoltage, poor total power factor, and cross-talk. The addition of a reactor to the output of a drive will dampen overshoot peak voltage, reduce motor heating and audible noise, helping to extend the life of the motor.

Electrical Safety On-Line Training Seminars
Associated Research, Inc., Lake Forest, Ill., recently announced the expansion of its educational training seminars. Responding to requests for coverage of more applications, Associated Research has decided to expand these seminars to a full day training program. With these seminars, Associated Research will provide a comprehensive overview on electrical safety testing, including common shock hazards, commonly performed tests, how to correctly set up a work station, and how to ensure that an operator is properly trained. With their increased scope, the regional seminars add further analysis of real life applications, more demonstrations of the test equipment found in the field, and actual examples of workstations. The seminars provide the most in-depth training available on electrical safety testing and are applicable to anyone who is involved in electrical safety testing at any level. Associated Research is also now offering free web based seminars throughout the year. These new "Webinars" will provide detailed and focused information on a variety of issues concerning electrical safety testing including a comprehensive look at individual electrical safety tests such as the hipot test and the ground bond test. They will also thoroughly discuss how to ensure that an operator is properly trained, a test station is properly set up, and that tests are being performed in a safe manner. Both the seminar and webinar programs will be presented by Dwayne Davis, Technical Services Manager, who has over 35 years of experience with high voltage products.

Industrial Power Supplies
Advanced Power Solutions (APS) recently announced a new family of industrial power supplies delivering peak loads up to 900W from a family of 500W - 800W switchers. These U-Frame products measure only 4.33 x 8.00 x 2.50 in. (optional cover and fan is larger). The APS500/600/800 family of flexible power supplies offer standard options, including U-frame or covered with fan package; IEC-320 inlet with switch, terminal block or molex connections; constant voltage or constant current operation; status and control signals like remote sense, current share, power good and remote on/off control; and internal diodes for redundancy. These supplies are ideal for industrial "bulk power," networking "distributed-power," and telecommunications "battery-charging" applications where high small size and high power density is required. With efficiencies up to 83%, these supplies generate little heat and require only 30cfm airflow for cooling, reducing system temperatures while increasing system reliability. These supplies feature universal AC input with active power factor correction for EN61000-3-2 (Class A) compliance; operating temperatures from -20°C to 50°C; built-in over-current, over-temperature, and over-voltage protection circuits; international safety standards (UL/cUL60950, EN60950) and bear the CE Mark (LVD); and Class B emissions.

SNMP/HTTP Agent Devices for UPSs
Falcon Electric, Irwindale, Calif., recently introduced new internal and external SNMP/HTTP agent devices with enhanced features. The new SNMP agents provide users a higher level of remote monitoring and management of Falcon on-line SG Series™ UPSs across a LAN, WAN, Enterprise Network or over the Internet, using any web browser (HTTP), SNMP, or Telnet. The new SNMP/HTTP/Telnet agents now are supplied with client software supporting the in-band safe shutdown of any LAN connected server or workstation running Windows 2000, XP, Server 2003, Small Business Server, Solaris (Sparc and X86), SCO (OpenServer and UnixWare), Novell 5x-6x and Linux. If used with the purchased agent device, the client software may be loaded onto as many servers or workstations as desired without additional licensing fees. The internal SNMP/HTTP/Telnet agent easily installs into an option slot located on the rear panel of all Falcon SG Series models. External agents simply connect to the SG Series' RS-232 ports using a supplied cable. The TCP-IP addressable agents give users the ability to remotely manage an unlimited number of Falcon UPSs from a central location. They interface using a standard Ethernet 10/100BaseT jack and support both DHCP and Static IP. They can also be connected to any 802.11b/g wireless network bridge, freeing the user to place the UPS anywhere within his/her facility. The SNMP UPS is MIB II compliant and ships with a "snap-in" management information base (MIB) for HP OpenView, and IBM NetView Network Management Software (NMS). The agents support remote UPS monitoring, UPS testing, UPS temperature monitoring and settable alarms, programmed shutdown and startup, battery management and replacement date, power history and event reporting; automatic notification of alarm conditions (through trap IP addresses), remote agent management, multi-level security and much more.
