Stand-alone balancing for whole packs, off the battery
Mains-powered bench instruments that balance a pack on the workbench before it is closed. Each channel of the pack is wired to the terminal strip, the unit reads every cell, and it runs discharge, constant-voltage or charge balancing until the strings match — then stops and alarms by itself. String count is recognised automatically, so one unit covers a whole range.
Mechanism: Resistive and PWM-pulse discharge with an isolated multi-tap cell bus; ±(0.08%+0.06%)FS cell acquisition.
5 A NY-FD04AS24G · 2S – 24S
The simplest of the bench range: a fixed 5 A resistive discharge balancer for 2S–24S packs. Wire every tap to the terminal strip, start it, and it brings the strings down to match without any current to set.
1 – 7 A NY-FD24SCG-7 · 2S – 24S
Same discharge-only topology as the FD04AS24G but with a 1–7 A adjustable balance current, so you can match the discharge rate to how much capacity has to come off the pack.
0.1 – 14 A NY-FD14AS24CK · 2S – 24S
The highest-current instrument in the range at 14 A, and the only one that can balance upward: a PWM pulse discharge path plus a charge-balancing mode that tops the weak cells back up. Needs an external charger that can be adjusted and stopped automatically.
0.1 – 7 A NY-FD07AS24CK · 2S – 24S
The three-mode CK instrument at 7 A. Same discharge, constant-voltage and charge balancing as the FD14AS24CK, for shops that do not need the extra current headroom.
0.1 – 7 A NY-FD07AS48CK · 2S – 48S
The 48-string version of the CK instrument, for storage and telecom packs that no 24S unit can reach. Runs from a DC 220 V supply rather than the pack’s own voltage range.
