Battery Chargers. Available for 12, 24 or 48-VDC
battery systems at power levels of 300, 600 or 1.000 watts. Source
voltages include 110 or 220 VAC, 12, 24, 48, 110 or 250 VDC. Charging
profiles are selectable between 2 and 3-stage, and include manually
initiated equalize. Temperature compensation is standard. The 300-watt
models (BCA310 & BCD310) are wall-mountable. The 600 and 1000-watt
models (BCA610, BCA1000, BCD610 & BCD1000) are available as wall mount
or rack mount units.
DC-DC Voltage Converters. We offer negative step-down models
ranging from 60 to 600 watts (common negative step-up models range from
120 to 600 watts). Fully-isolated models are available in 5 and 7 amps
(VTC120i & VTC120ih Series). 600 and 1000 watts (VTC610, 615, 1000 and
1015 Series) are available in rack mount and come standard with digital
volt and amp displays.
Power Supplies. Systems from 110 or 220 VAC are available in 120,
240, 300, 600 and 1000 watts. The 120, 240 and 300-watt models are
available in wall mount only. Digital Voltage and Current Displays are
optional for the 300, 600 and 1000-watt models. The 600 and 1000-watt
models are available in wall or rack mount and include the digital
displays as standard.
Inverters. Our inverters have a multi-stage filter on the input
and output, and have large hold-up capacitors on the internal 200 VDC or
400 VDC rail for complete elimination of the 60 Hz ripple on the
inverter input. In addition to quality of workmanship, this concept
indicates that our inverters comply fully with EMI requirements for EN
55022 Class B with a significant dB margin. The audio frequency range
noise (C-message) on the input is also very low.
