ページを印刷するThe IQ DC Power Supply is a dc to ac inverter module
intended for operation of ac powered devices from a dc
supply. The unit will operate the Cutler-Hammer
MP-3000, IQ 1000 II, URTD, IQ Data Plus, Assemblies
Electronic Monitor, or other ac-powered equipment
requiring no more than 30VA of power at any power
factor.
NOTE: It may not be suitable for energizing devices
requiring inrush currents over 1 A (e.g., some contactors
and relays).
FEATURES
Handles input voltages ranging from 40Vdc to 250Vdc
with no need to set switches or jumpers.
The ac output is isolated from the incoming power.
Two LEDs provide operating and troubleshooting
indications.
Withstands output short circuits, while providing
ample power to start loads with inrush up to 1 A.
Effective 7/98
Instructions for IQ DC Power Supply
SPECIFICATIONS
Rated Supply Voltage: 40Vdc to 250 Vdc. Operates from
38 Vdc to 275 Vdc.
Output: Square wave, 60Hz, 125Vac
Output voltage varies less than + 2% as a function of dc
supply voltage within rated range.
Output voltage varies less than + 5% per 100mA load
change.
Rated Power Output: 30VA, at any power factor.
Ambient Temperature Range: 0
Maximum Lead Length: Input: 35 ft of #14 AWG.
Output: 100 ft of #14 AWG.
Protection Limits: Average output current is limited to 0.4
A. After an average current overload, unit cools itself for
approximately 2 minutes and restarts. Peak short-circuit
output current is limited to 1 A on a cycle-by-cycle basis.
INSTALLATION
This device is designed to be installed, operated, and
maintained by adequately trained workmen. These
instructions do not cover all details, variations, or
combinations of the equipment, its storage, delivery,
installation, check-out, safe operation, or maintenance.
Care must be exercised to comply with local, state, and
national regulations, as well as safety practices, for this
class of equipment.
CAUTION: Remove all power from the device to
which the IQ DC Power Supply is being connected;
otherwise, serious or fatal personal injury and
equipment damage may result.
The IQ DC Power Supply should be fastened securely in
place before operating. Locate the module in an area
where air can freely move about the unit.
While mounting the unit absolutely NO power should be
connected. See Figure 1 for mounting holes.
