Connecting primary windings in parallel
When primary windings (Wpri) are connected in parallel, DCR decreases,
Irms increases, and inductance and volt-time product remain the same.
Example: For HPH6-2400L, connect three primary windings in parallel:
Inductance = Inductancetable
= 194 H
DCR = 1
÷ [Wpri × (1 ÷ DCRtable)]
= 1
÷ [(3 × (1 ÷ 0.030]) = 0.010 Ohms
VT
= VTtable
= 131.9 V-sec
Irms = Irmstable × Wpri
= 2.90 × 3 = 8.70 A
Connecting secondary windings in parallel
When secondary windings (Wsec) are connected in parallel, DCR
decreases and
Irms increases.
Example: For HPH6-2400L, connect three secondary windings in
parallel:
DCR = 1
÷ [Wsec × (1 ÷ DCRtable)]
= 1
÷ [(3 × (1 ÷ 0.030)] = 0.010 Ohms
Irms = Irmstable × Wsec
= 2.90 × 3 = 8.70 A

Formulas used to calculate electrical characteristics
Connecting windings in series
Inductance = Inductancetable × (number of windings)2
DCR = DCRtable × number of windings
Isat = (Isattable × 6)
÷ number of windings connected in series
Irms = Irmstable
Connecting windings in parallel
Inductance = Inductancetable
DCR = 1
÷ [number of windings × (1 ÷ DCRtable)]
Isat = (Isattable × 6)
÷ number of windings connected in series
Irms = Irmstable × number of windings
