分流器 FLUKE Y5020
厂家：美国福禄克

简介：
The Model Y5020 is a precision, four-terminal, current shunt designed for use in calibrating ac/dc current sources in the range of 0 to 20 amps, do to 5 kHz. The shunt is housed in a forced-air cooled, PTI (Portable Test Instrument) case. This case is compatible with all instruments in the Fluke PTI product line and can be stacked with other PTI products to form a portable test system.

Forced-air cooling is accomplished by a fan mounted on the rear panel. Air is pulled in through the fan, passed over the shunt, and exhausted through the rear panel. Power for the fan is derived from the power line. Two voltage configurations are available, 115 or 230V ac ±10%, 50 to 60 Hz.

Four front panel terminals provide electrical access to the shunt; two are current input terminals and two are voltage output (sense) terminals. When the shunt is connected into a circuit and operating at its maximum current limit (20 amps), the input connections and the shunt present a burden voltage of less than 0.25V dc.

SPECIFICATIONS

Specifications for the Y5020 Current Shunt are given in Table 1.

INSTALLATION

The Y5020 PTI case is designed to stack with other Fluke instruments in the PTI product line. Use the following procedure to stack the Y5020 with the other PTI instruments.

1. Locate and pull the black latches on both sides of the unit to their extended position.

2. Place the unit on top of the PTI stack with the front panel toward the front of the stack.

3. When the unit is properly seated push both latches to the in position. This will lock the Y5020 to the stack.

OPERATING NOTES

Input Power

Line power requirements for the Y5020 are specified on a decal located on the bottom side of the unit. These include line voltage requirements (115V or 230V ac ±10%, 50 to 60 Hz) and replacement fuse types. Input power is used solely to power an internal cooling fan. A front panel POWER switch allows the fan to be turned on and off.

Fuse Replacement

The Y5020 includes a fuse to protect the ac power line from an accidental overload. If replacement is required, use a 1/8 amp, 250 volt (AGC) fuse. Use the following procedure to replace the fuse:

1. Set the POWER switch to OFF and disconnect the unit from line power.

2. Locate the fuse holder on the rear panel.
