Page 7: Description Of Equipment
DESCRIPTION OF EQUIPMENT Electrical Specification Variable 3 Phase Supply Timer Control Output Control Construction... - Page 8 Electrical Specification 1.1.1 The supply voltage for the equipment is 415V (380v if requested) , 3 phase, 50/60Hz. The unit will tolerate an input voltage variation of ± 6%. IMPORTANT: The Unit Must be Connected to a 4 Wire Supply. 1.1.2 The maximum power supply requirements will be 1100VA per phase.
- Page 9 Variable Three Phase Output 1.2.1 There are three independently controllable outputs available from the equipment. These outputs are 120º apart electrically. 1.2.2 The equipment's output terminals are located on the top edge of the front panel. Each terminal is clearly marked showing the output phase and polarity. 1.2.3 Each output phase is controlled by moving the appropriate regulator control knob in a clockwise direction.
- Page 10 Timer Control 1.3.1 The timer system will have the following parameters: Range: 0-999.999 seconds (Quartz locked) Resolution: 0.001 seconds Accuracy: Contact mode ± 2ms Current mode ± 3ms for test currents 20-40% on each range Current mode +3ms or -1ms for test currents 40-100% on each range NOTE: Timing results obtained with test currents below 20% of the selected ammeter range, and on measured times of 19ms and below, are of...
- Page 11 Output Control 1.4.1 The output from the unit is controlled by the illuminated output ON and OFF push-buttons. These push-buttons are located on the front panel of the unit. 1.4.2 The output is automatically switched off by the following actions: Depressing the OFF push-button.
