| Noise Rejection |
With unit under power and the isolation transformer configured for a transformation
ratio of 1:1 and with an ANSI/IEEE C62.41, Category A pulse applied either normal mode
or common mode at the input, the noise output voltage will be less than 10 volts normal
mode and less than .5 volts (½ of one volt) common mode in all four quadrants
(CM-NM, NM-NM, CM-CM, NM-CM). |
| Surge Voltage Withstand |
Tested under power to ANSI/IEEE C62.41, Category A & B (formerly IEEE587-1980).
Power conditioner tested to withstand up to 6000 volts @ 3000 amp ringwave and unipo
lar impulse. |
| Construction Materials |
Transformer wires are copper and insulated with Class H materials. Windings are insu
lated with Nomex paper insulation before vacuum varnishing. Internal wiring is a minimum of 200 degree C rated and sleeved with Class H materials. Grain oriented
silicon iron cores are constructed using 14 mil. laminations interleaved one to one. Eddy
currents are minimized and external magnetic fields are below 0.1 oersted (at 12 inches
distance in any direction). |

* Supply breaker ratings are determined by NEC guidelines limiting breaker loading to 80% of rated breaker capacity. Calculations for supply breaker recommended
ratings are based on input full load amps multiplied by 1.25 and then selecting the next larger standard size breaker. Wire sizes shown in the input and
output connection tables of this specification sheet are the minimum sizes allowed by electrical codes for each supply breaker rating and are taken from the 2002
National Electrical Code Article 310.16 table references for use in 90° C installations.

Breaker Trip Current Programming (when applicable)
Some models of power conditioner may support an optional programmable circuit breaker. If so equipped
reconfiguring the settings of a programmable circuit breaker (when required) is accomplished by changing the
settings of DIP switch pack I1 on the front of the circuit breaker. Each circuit breaker has a maximum ampacity
rating, and the DIP switches may be set to program the circuit breaker to trip at increments of 100%, 95%, 90%,
80%, 70%, 60%, 50%, and 40% of the breaker’s maximum input ampacity as shown to the left below. The input
circuit breaker of each model of GPI Series 2000 is programmed for the appropriate trip current as determined by
the input voltage available at the installation site. Consult the following table.

DIP switch pack I3 defines the circuit breaker’s inrush current capability. I3 consists of three DIP switches, which allow the breaker to be programmed to accommodate inrush current characteristics from zero to twelve times its rated steady state ampacity as shown to the left. The GPI Series 2000 utilizes a low impedance isolation transformer, which, when energized, results in substantial short-term inrush current. I3 DIP switches are factory set so that the circuit breaker is configured for maximum inrush current capability. POWERVAR recommends that these settings not be changed without first consulting POWERVAR Technical Support. |
 |
DIP switch pack t1 determines the circuit breaker’s response time to an overload condition. Response times of three seconds, six seconds, twelve seconds, and eighteen seconds may be selected as shown to the left. The t1 DIP switches are factory set for a response time of eighteen seconds. POWERVAR recommends that these settings not be changed without first consulting POWERVAR Technical Support. |
