Description
The CSN Series of closed loop current sensors are based on the principles of the Magnetoresistive or Hall effects, and the null balance or zero magnetic flux method (feedback system). The magnetic flux in the sensor core is constantly controlled at zero.
The amount of current required to balance zero flux is the measure of the primary current flowing through the conductor, multiplied by the ratio of the primary to secondary windings.
This closed loop current is the output from the device and presents an image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resistor.

Features
*Current sensing up to 1200 amps
*Measures ac, dc and impulse currents
*Competitive cost/performance ratio
*Rapid response
*High overload capability
*High level of electrical isolation between primary and secondary circuits
*Industrial operating temperature range
*Small size and weight

Typical Applications
*Variable speed drives
*Overcurrent protection
*Ground fault detectors
*Current feedback control systems
*Robotics
*UPS and telecommunication power supplies
*Welding power supplies
*Automotive - Battery management systems
*Wattmeters

Description
The Gamewell-FCI Power Supply 9 (GFPS-9) panel provides two (2) Class A, Style Z, or four (4) Class B, Style Y notification appliance circuits. Each circuit is rated at 3 amperes, with a total capacity of 9 amperes per panel. These circuits may be programmed to activate by groups or various combinations by connection to one (1) or two (2) existing Class A or B notification appliance circuits with operating voltages ranging from 9 to 30 VDC. Either noncoded or coded operation is possible. In addition, the GFPS-9 can provide a temporal pattern output from a noncoded input.
A unique feature allows for programmable synchronizedoutputs for strobes by three (3) different major manufacturers, System Sensor, Faraday, or Gentex.
The GFPS-9 contains its own battery charger capable of maintaining batteries of up to 33 AH. The cabinet provides space for a set of 7 A/H batteries. It is supervised for ground fault, over-current, open circuits and low battery conditions. These conditions light the appropriate trouble
LED and automatically open the notification appliance circuit used for activation, transmitting a trouble signal to the main fire alarm control panel. The ground fault detection circuit may be disabled.
The unit contains a set of dry, Form “C” trouble actuated auxiliary contacts, rated 2.5 amp. @ 24 VDC (resistive). Transfer of these contacts for AC power failure is programmable and can be delayed for a period of six (6) hours. This delay feature may be disabled.
A power limited, non-resettable auxiliary power output up to three (3) amperes is also available. The panel can be programmed via DIP switch to disconnect this output from the
batteries 30 seconds after AC power failure, in order to avoid running down the batteries from current devices such as door holders, etc.
